Creativity and

Innovation:

The Key to ICT

Advancement and Social

Wellbeing

SummaryCreativity and Innovation are the keys to continued advancement of human societies and their wellbeing.

Information and Communication Technologies (ICT) have assumed a key role in the advancement of all

societies today. Engendering the spirit of creativity and innovation is more important than ever before asinternationalization of industry and education takes hold; however, social structures, and educational

paradigms used in most countries work against the spirit of innovation. Chris Stevens defines creativity as

the ability to generate and use insight. To some extent everyone is capable of being creative; however,

most people do not exploit their full creative potential, as they do not have a clear process to guide and

sustain the flow of their creative juices. Joyce Wycoff says that innovation is a mental extreme sport;

therefore, like all good sports persons, innovators need to train their body, mind and spirit to do it well.Wycoff adds that innovation requires pulling unrelated things together; thus, to innovate, one must have

a wide range of interests, as a corollary narrow focused programs and courses hinder innovation. In this

seminar we will investigate how creativity and innovation can be embedded in as an educational paradigm,

and in particular for Information Technology education.

PresenterProf. Nalin Sharda gained B.Tech. and Ph.D. degrees from the Indian Institute of Technology, Delhi.

Presently he teaches and leads research in Multimedia and Internet Communications at the School of

Computer Science and Mathematics, Victoria University, Australia. Dr. Sharda publications include the

Multimedia Information Networking textbook, and around 100 papers and handbook chapters. Nalin has

invented Movement Oriented Design (MOD) paradigm for the creation of effective multimedia content

based experience, and applied it to e-Learning and other applications. Nalin is leading projects for the

Australian Sustainable Tourism CRC, to develop e-Tourism using Semantic Web technologies, andinnovative visualisation methodologies. Nalin has been invited to present lectures and seminars in the

Distinguished Lecturer series of the European Unions Prolearn program. He has presented over fifty

seminars, lectures, and Key Note addresses in Austria, Australia, Finland, Germany, Hong Kong, India,

Innovations in AffordableWireless Broadband Access

Technology evolution in Wireless Access Networks and demand for Broadband Internet Services is moving

forward rapidly. With increased competition among operators to attract subscribers, there is an increased

need to choose a technology that differentiates him from others, in terms of contemporary services it offers

to subscribers and the cost at which it is offered.

In Wireless Access Networks, with the increased demand for spectrum, a technology which is spectrally

efficient and can pack more bits/Hz is the key. On the other end, it should also be able to provide toll-quality voice, and all types of Internet services ranging from Voice over IP, Video on Demand, Multicast

services like - Video conferencing, Internet Radio, and so on. Another major challenge in todays scenario

with the wireless access technology is the rate of obsoleteness the time period after which the technology

needs upgradation to support new services.Midas Communication Technologies building on its expertise of 15 years continues to innovate in

affordable wireless technology solutions. corDECT (a DECT based Wireless Local Loop technology,

providing Toll-Quality Voice and simultaneously 35/70 kbps Internet service) and BroadbandcorDECT

(providing simultaneous Toll-Quality Voice and 256/512kbps Internet Service) are the result of these

innovations.BroadbandcorDECT was developed by providing proprietary extensions to the standard ETSI DECT Protocol

Stack (ETS 300-175 series) at Physical, MAC and DLC layers to provide a capacity of 2.88 Mbps

(Uplink+Downlink) per carrier per sector, with a spectrum utilization of 1.66 bits/sec/Hz. It incorporates

adaptive multi-level GFSK modulation (2/4/8 level modulation, which can carry 1/2/3 bits per symbol),Hybrid ARQ and Packet scheduling based on Channel Quality and link budget. This system also provides

polarization diversity with selection between Horizontal and Vertical Polarization, adding to the time and

frequency dimension. Fast Channel setup at the MAC layer (of the order of 20ms) ensures that the system

can operate in Always ON mode where the network connections are retained logically while physical

connections are suspended when there is no traffic. Further, MAC bearers can be increased or decreased

to carry application payload.BroadbandcorDECT supports contemporary internet services such as Voice Over IP, Video On Demand,

Multicast services, etc. System implements VLAN (802.1q, 802.1p), Multicast, Routed and Bridged mode of

operation supporting PPPoE/DHCP mode of access, Security features such as ARP spoofing,

Broadcast/Multicast Strom Control, Access Control List (ACL). To improve throughput system implements

IP header compression and payload compression.BroadbandcorDECT architecture implements advanced end-to-end QoS (Quality of Service), for delivery of


8/50

delay and jitter sensitive applications. Apart from the regular policing and scheduling of traffic based on

the class, the class is also mapped to the physical level service flows. The physical level QoS includes ARQ

with various timeout to suit a particular application, and wireless traffic scheduling. These advanced QoS

features provide real-time, non-real time, high reliable channels for delivery traffic from various Internetapplications.BroadbandcorDECT architecture is Internet Centric and also is future proof such that when air-interface

bandwidth increases, the traffic can still be carried through by the same infrastructure, thus enhancing the

Return On Investment (ROI) for the operator and reducing the Rate of Obsoleteness.

In the process of continuous innovation, next in Product line BroadbandcorDECT NG supporting data rates of

1 Mbps per subscriber uses reconfigurable RFIC and baseband platform allowing full compatibility with

DECT to IMT 2000 evolution and beyond. Innovation in MAC architecture will allow intelligent

multiplexing on a per session basis between ARQ and FEC schemes on the fly, purely based on SNR and

CIR [Midas/IIT IPR].

BioA. Balaji received his B.E. degree in Computer Science and Engineering from Madurai KamarajUniversity, India in 1993. He received his M.S. degree in Computer Science from the Indian Institute of

Technology, Madras, India in 1999. He was employed by Future Software Pvt Ltd., Chennai, India during

1993-94. While at IIT Madras he was working as Senior Project Officer for the corDECT project. Since

1998, he has been with the Midas Communication Technologies Pvt. Ltd, Chennai, India as Manager. He is

currently working for the BroadbandcorDECT project.

NGN Revolution challenges and

opportunities

Abstract

As the shift to all IP based networks takes place it brings some interesting set of challenges to Service

providers and Network Equipment providers, The Telecom market is a dynamic market, currently driven by

gaining consumer market share via attractive Services offerings. However just the introduction of services

is no longer enough for differentiation in such a competitive market place. The value proposition is

shifting from connectivity to the quality of experience and time-to revenue is becoming critical factors for

differentiation. By leading these shifts, the internet vendors such as Google, Myspace.com, Skype, Yahoo,MSN etc. are taking bite out of the service providers revenue. These forces are driving major

transformations in the Telecommunication industry which are rapidly changing the rules for competing.

To differentiate, service providers really need to focus on strategic service areas with long term planning in

place. The convergence of the telecom infrastructure toward a more open, IP-focused IT architecture is one

likely scenario that will play out in the industry hence the need for deployment of applications such as IMS,IPTV, Rich Content, VoD, SDP etc. is much more essential at this point of time. The transition toward an

IT-like structure where any application can run over many different types of network transport will

revolutionize new service creation in the telco community.

BiosRavinder Sabhikhi is a Distinguished Engineer at IBM. His current assignment is CTO for Next generation

Networks for the Asia Pacific. He has over 25 years of experience in system architecture, design,

developing and leading teams of engineers in the development of world class networking products.Ravinder holds several patents in the field of networking, he has received bachelors and masters in

Computer Science and Masters in Business Management from NC State University USA.

Dr. Suthikshn KumarPESIT, Bangalore

Abstract:

Whats fishing, cooking, gardening, eating, car repairing, butterflies, telescope, monkeys, frogs, etc got to do with

teaching Engineering courses? In this tutorial, we build interesting analogies from real world to make the job of

teaching very interesting. Analogies are a way of explaining something by comparing it to something else. This

technique also uses partial similarity. For example, we may give an analogy of bird for explaining how airplane

works. Case Studies are presented to students to improve their understanding of the subjects. In going through case

studies, we learn from others experiences. We present some interesting analogies and case studies for specific subject

of Mobile Communication. The tutorial is based on speakers experience in teaching Masters and Bachelors

students. The tutorial is supplemented by resource CD on Mobile computing.

Abstract:

This tutorial aims at the usage of Programmable System On Chip (PSOC) in an Embedded System Design.PSOCIntegrated Circuits (ICs) consists of many Mixed Signal Arrays with On Chip Controller devices. These devices are

designed to replace multiple traditional Micro-Controller Unit (MCU) based system components by a low cost single-chip programmable component. A PSOC device includes configurable blocks of analog and digital logic as well as

programmable interconnects. This architecture allows the user to create customized peripheral configurations to

match the requirements of each individual application. Additionally, a fast Central Processing Unit (CPU), Flash

program memory, SRAM data memory, and configurable Input/Output are included in a range of convenient pin out.

We have carried out the experiments for the validation of Analog to Digital Converter (ADC), Digital to Analog

Converter (DAC) and their characteristics. We have also interfaced Encore-II with another PSOC, where Encore-II

itself is a PSOC. The register and memory contents of Encore-II were read / written with the help of a PCs hyper

terminal. The results were found to be satisfactory.

Simulation of DSDV, AODV and DSR Routing Protocols InAd-hoc Network

Shyam Lal*, NIT,Kurukshetra-india,[email protected]

This paper presents the simulation of DSDV, AODV and DSR routing protocol in ad-hoc network using NS-2 simulation. An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporarynetwork without the use of any existing network infrastructure or centralized administration A simulationmodel with MAC and physical layer models is used to study interlayer interactions and their performanceimplications. The On-demand protocols, AODV and DSR perform better than the table-driven DSDVprotocol. Although DSR and AODV share similar on-demand behavior, the differences in the protocolmechanics can lead to significant performance differentials. The performance differentials are analyzedusing varying network load, mobility, and network size.

Highly Dynamic Multivalued Unified Vector Routing ForAd-Hoc networks Naga Raju*, Kits,

[email protected]

Abstract Mobile Ad-Hoc networks are combination of wireless nodes which dynamically exchange data -among themselves with out any centralized access point. In this paper we describe an idea of constructingmulti path [1] routing from source to destination node in Mobile Ad-Hoc networks with the help of qualitativemetric We have made changes to Highly Dynamic Distance vector routing vector algorithm [2] to alsosatisfy the requirements of mobile ad-hoc networks. In DSDV every node periodically broadcast currentassociated statistics to its neighbor nodes. We transform the attributes values of the statistics in to unifiedranks [3], the average of unified rank is treated as a qualitative fitness value of the link. Routing decisionprocess has been enhanced by embedding this proposed qualitative fitness metric for selection of multiplepaths in DSDV for efficiency (increase the reliability of data transmission or to provide load balancing).Index terms: Multipath, unified rank, qualitative fitness.

Abstract: The growth in wireless communication technologies attracts a considerable amount of attention inmobile adhoc networks. All mobile hosts in an adhoc network are embedded with packet forwardingcapabilities. Typical applications of these networks are outdoor special events such as conferences,concerts and festivals; places with no network infrastructure; cases of emergencies and natural disasters;and military maneuvers. It is decentralized and independent of infrastructure. Since mobile hosts in anadhoc network usually move freely, the topology of the network changes dynamically and disconnectionoccurs frequently. These characteristics make it likely for a mobile adhoc network to be separated intoseveral disconnected partitions, and the data accessibility is hence reduced. Several schemes have beenproposed to alleviate the reduction of data accessibility by replicating data items. Although the previousalgorithms consider no restriction on the memory space in each mobile node for replication, it isimpracticable. In this paper an attempt is made in studying two replication algorithms in which the memoryspace is restricted. Later an improvement over these protocols using threshold value is considered.

MANISH MADHUKAR*,SMIT,SIKKIM;BINDU AGARWALA,SMIT,SIKKIM; SANGAPPABIRADAR, SMIT,[email protected];[email protected];[email protected]

A Mobile Ad-Hoc Network (MANET) is a decentralized network of autonomous and self organized wirelessnodes. The paper tries to state about the performance of TCP with moving gateway in an adhoc network.The TCP with mobile IP gives the mobility support to the adhoc nodes. The moving gateway works as acommon gateway for rest of the nodes that send traffic using the closest neighbors through all nodes that iswithin the range of intermediate node(s). The hop-to-hop transfer mechanism is continued throughout thenetwork until destination is not reached. If any node is not receiving data in any way, it means the node isnot connected with the gateway.

Security is an essential service in both wired and wireless communications. The success of ad-hoc andsensor networks strongly depends on the peoples confidence in its security. However the characteristics of


19/50

ad-hoc networks pose challenges and opportunities in achieving security goals, such as confidentiality,authentication, data integrity, availability, access control and non-repudiation. Authentication in ad-hocnetworks is a core requirement for secure protocols and secure applications of ad-hoc networks. Thus

security in ad-hoc networks is the main focus of this work. The paper gives an overview of the existingefficient security protocols suitable for both ad-hoc and sensor networks: Zero Common Knowledge(ZCK)protocol, Identity Certified(IC) Authentication protocol, SPINS. The last section of the paper discusses thechallenging threats to ad-hoc and sensor networks which gives an in- depth analysis as to how robust anauthentication protocol should be.

Signal Stability based QoS Routing (SSQR) for Mobile AdHoc Networks

Giriraj Chauhan*, IIT Guwahati;Sukumar Nandi, IIT [email protected];[email protected]

We propose an on demand quality of service (QoS) routing scheme named signal Stability based QoS

Routing (SSQR), that provides QoS support in terms of bandwidth and end-to-end delay in mobile ad hocnetworks (MANETs). SSQR is designed over Signal Stability based Adaptive Routing (SSA) and aims tofind and maintain stable QoS routes in ad hoc network. The main objective of SSQR is to select QoS routesthat can survive for longer period of time. This is accomplished with the help of signal stability whichconsists of signal strength and link stability . The performance of SSQR is extensively investigated bysimulation in NS-2. Our results validate that SSQR represents an important improvement by selectinglonger-lived QoS routes in mobile wireless networks.

In a dynamic heterogeneous environment, such as pervasive and ubiquitous computing, context-aware adaptation is a key

concept to meet the varying requirements of different users. Connectivity is an important context source that can be

utilized for optimal management of diverse networking resources. Application QoS (Quality of service) is another

important issue that should be taken into consideration for design of a context-aware system. This paper presents

connectivity from the view point of context awareness, identifies various relevant raw connectivity contexts, and discusses

how high-level context information can be abstracted from the raw context information. Further, rich context information

is utilized in various policy representation with respect to user profile and preference, application characteristics, device

capability, and network QoS conditions. Finally, a context-aware end-to-end evaluation algorithm is presented for

adaptive connectivity management in a multi-access wireless network. Unlike the currently existing algorithms, the

proposed algorithm takes into account user QoS parameters, and therefore, it is more practical.

Path planning and obstacle avoidance are the two major issues in any autonomous navigation system. Thisnecessitates the use of (i) multiple sensors on a robust and real time processing platform which is

computationally efficient; and (ii) a set of heterogeneous actuators. Also, conflicting specifications must beconcurrently met. We present here a design methodology for an embedded system-on-chip and itsimplementation targeted for an autonomous navigating robot. The concern is to meet constraints such aspayload, placement, response time, throughput, power consumption and control.

[email protected]

The concept of applications that can operate independently and automatically with minimal humaninteraction find appeal in various areas ranging from home to the far frontiers of the space. One such areais remote temperature monitoring. The solution uses the TINI a Java enabled embedded computerconnected to a network of 1-wire devices. The TINI is used to collect and transfer data to a remote serverfor storage and processing, using either a wired or a wireless interface. The 1-wire devices connected toTINI can be accessed any time over the network by using application like web browser where the TINI actsas a platform providing the communication. The system also provides an instant visual feedback via a localLCD display connected to a serial port of TINI for real-time monitoring. The modular approach followed inthe development of the system allows additional 1-wire devices to be integrated to the present system.

Centralized Resource Discovery usingMobile Agents in Grid and its EfficientRetrieval

Deepak Khandelwal*, IIT Roorkee; Padam Kumar, [email protected]; [email protected]

A computational grid system is basically an infrastructure that facilitates sharing of networked resources andlocation-independent access to these resources. Resource Discovery forms a very important part of such asystem. Majority of the existing techniques in use for resource discovery are reactive in nature, i.e. they cause arequest for a resource to initiate the discovery of resources at various sites of in the grid. In this paper, we haveproposed a framework which offers a proactive approach to resource discovery. We have discussed the designof a module Service Repository that may be maintained at a single or multiple sites that stores the freshestpossible information about the availability of resources throughout the grid. This data is kept as fresh as possible

with the use of Mobile Agents that are created and dispatched for various sites for the purpose of gatheringresource related information from those sites. The several different techniques in which this can be done arediscussed along with the pros and cons of each. Efficient retrieval of the accumulated information also plays avery important role. We have proposed a novel usage of trees to efficiently process the query of a site thatcontacts the Service Repository to check for availability of resources in the grid. We have implemented themobile agents using Java Aglets.

Computationally EfficientMCTF for Scalable VideoCoding Karunakar K*, MIT; Kumkum Garg, Mit Manipal

[email protected]; [email protected]

In 3D-wavelet video coding framework, the temporal filtering is done along the trajectory of motion usingMotion Compensated Temporal Filtering (MCTF). Hence computationally efficient motion estimationtechnique is the need of MCTF. In this paper a predictive technique is proposed in order to reduce thecomputational complexity of MCTF framework, by exploiting high correlation among the frames in a GroupOf Picture (GOP). The proposed technique applies coarse and fine search of any fast block based motionestimation to the first pair of frames in a GOP. The generated motion vectors are supplied to nextconsecutive frames and only fine search is carried out around those motion vectors. Hence coarse searchis skipped for all the motion estimation in a GOP except for the first pair of frames. The technique is testedfor different fast block based motion estimation algorithms over the different standard test sequences. Thesimulation result reveals substantial reduction (i.e. 41% to 66%) in the number of search points of motionestimation without compromising the quality of the reconstructed video compared to non-predictive

techniques. Since the motion vectors of all the pair of frames in a GOP except the first pair will have value1 around the motion vectors of the first pair of frames, the number of bits required for motion vectors arealso reduced by 50%.

This paper presents an iterative method for tracking and classifying human activities in a video sequence.The basic idea is that activities can be positively identified from a sparsely sampled sequence of a few bodyposes acquired from videos. Connected Graph representation has been used to store the 2D humanposes. Then these samples are matched against the graph abstractions derived form the frame wheremotion is identified in the video sequence. Sum of Absolute Differences method is used for motiondetection in video frames. The probability of false activity detection drops exponentially with the increased

Segmentation & Comparisonof Digital Video Ranjan Parekh*, Jadavpur University

[email protected]

Over the last decade there has been a huge proliferation on the use of multimedia content throughout theworld. As such an efficient and fast mechanism for retrieval of media content from multimedia repositoriesassumes fundamental importance. This paper addresses the problem of segmentation of digital video andtheir characterization for similarity comparison and retrieval in a video database. Segmentation of video todetect cuts and identify shots is done using differential values of adjacent frame contents. Thereafter theshots are characterized using features derived from Grey Level Co-occurrence Matrix (GLCM) computedfrom representative frames. A set of four directional normalized symmetrical GLCMs, one in each direction0, 45, 90 and 135, are use for computation of the features. Comparison of video content for similarity

retrieval is based on a combined set of GLCM features in an appropriate feature space.

Semantic Characterization ofVisual Media Ranjan Parekh*, Jadavpur University

[email protected]

Content based image retrieval techniques generally utilize low-level features to search, compare andretrieve images from databases. However the major limitation is that they fail to provide sufficientinformation about the semantic content of the media. Semantic characterization is necessary becausehumans tend to search or query for media based on their semantic features i.e. their meanings andassociations with real-world objects. However semantic concepts being based on human abstractions,

unique definitions for their characterization do not always exist. Moreover automated systems cannotdirectly understand the semantics inherent in media content. This paper proposes a methodology involvingvisual keywords whereby semantics can be inferred from visual media through comparison of low-levelfeatures.

In a content based storage and retrieval (CBSR) scenario, this paper addresses the problem ofclassification of environmental sounds. Even though a substantial amount of research work has been done

in the area of speech and music recognition, relatively less work has been done for environmental soundclassification. One reason for this is possibly the extreme difficulty in accurate classification due to the largevariations inherent in such sounds. This work uses statistical measures derived from zero crossing rate(ZCR) and root mean square (RMS) values of audio samples and plots them in a combined feature spaceto discriminate between three classes of environmental sounds.

COMPARATIVE ANALYSIS ON ALTERNATIVE

SCHEMES FOR USER AUTHENTICATION

Naveen Kumar*, Jamia MilliaIslamia, New Delhi;Prof. M.N. Doja, Jamia Millia

Islamia, New Delhi


Abstract-User Authentication is the procedure of determining whether a user should be allowed access to aparticular system or resource. Today, the alphanumeric passwords are used broadly for authentication, butother methods are also available, including biometrics, graphical passwords and smart cards, however,there are merits and demerits of these alternative technologies. Alphanumeric password basedauthentication system are simpler to administer and manage by user, As a result, these passwords areexpected to continue to remain so for some time [1]. With all these advantages alphanumeric passwordscontains well-known deficiencies with compromises on the security known as password problem[2].Graphical password ensures the high memorability of the user authentication, however the usability issuesare still focused area for research. Apart from these schemes biometric authentication promise the highestlevel of security but generally not affordable. We have studied and analyzed schemes those are mainly

based on what you know like alphanumeric password, graphical authentication and schemes based onwhat you know & what you are like dynamic signature verification, voice authentication, audio-visualauthentication and, password based on thoughts. This paper will be useful for information securityresearchers and practitioners who are interested in finding an alternative to user authentication schemes.

Network security is a complicated subject, historically only tackled by well-trained and experienced experts.However, as more people become wired, an increasing number of people need to understand the basics ofsecurity in a networked world. In this document we discuss some of the network security issues in TCP/IP.The Transmission Control Protocol/Internet Protocol (TCP/IP) [1] suite is a very widely used technique thatis employed to interconnect computing facilities in modern network environments TCP/IP is the language ofthe Internet. Anything that can learn to speak TCP/IP can play on the Internet. However, there exist several

security vulnerabilities in the TCP specification and additional weakness in a number of widely availableimplementations of TCP. These vulnerabilities may enable an intruder to attack TCP-based systems,enabling him/her to hijack a TCP connection or cause denial of service to legitimate users. We discuss

some of the flaws present in the TCP implementation of many widely used operating system and providerecommendations to improve the security state of a TCP-based system, e.g., incorporation of a timerescape route from every TCP state.

With the rapid growth of untrusted mobile environments, forward secure signature schemes havesignificantly received more attention than the ordinary digital signature which faces difficulties with keyexposure. The technique of forward security helps to mitigate the damage caused by the exposure ofsecret keys. The principle behind the Forward Security is that the secret keys are updated at regularintervals of time and it does not allow the adversary to break the scheme for any prior time period. This

survey paper provides a detailed description about the different types of forward security schemes andthen deals with the comparison of various generic forward secure schemes based on their individualrelative performances.

Mobile phones and handheld computers have become a target for attacks and a vehicle for malicious code.With the exponential growth of these device population combined with the convergence of networks, it will

be much devastating compared to PC based viruses, worms and Trojan horses. The trickle of maliciousprograms that embarked upon Symbian in 2004 has become a constant stream threatening to become atorrent spawning a multitude of families. The attacks could range from installing malicious software thatdeletes personal data, running up a victim's phone bill by making toll calls or sending a SMS/MMS todegrading or overloading mobile networks with denial of service (DOS). It took couple of decades forcomputer virus to evolve but only a couple of years for the mobile virus to cover the same ground. Thispaper introduces some of the pernicious Mobile Viruses, Worms, Trojans and their mode of propagation asa study. This paper also proposes how these malicious software can be prevented in a proactive way.

Many applications like pay-per-view, distribution of digital media etc., require secure group communicationservices in order to deliver packets from one or more authorized senders to a large number of authorizedreceivers. The main issue in secure group communication is group dynamics and key management. Ascalable secure group communication model ensures that whenever there is a membership change, newgroup key is computed and distributed to the group members with minimal computation and communicationcost. Handling member removal(leave) is more complex than member join event in any secure groupcommunication model. In this paper m-ary tree structure is used, with number of keys at each level beingm. Here, we address cumulative member removal(leave) and present protocols that minimize the numberof messages required to distribute new group key to remaining members in the group. The issues relatedto two members removal(leave) and cumulative arbitrary members removal are handled separately.

Signal Processing for Real Time Multi-channel GPS Software Receiver

.Rajeev Yadav*, Center for Air Borne Systems;Nomi Sonowal, Center for Air Borne [email protected];[email protected]

This paper describes a new approach for real time implementation of 12 channels tracking of GPS L1 C/APRN signals for software based GPS receiver on TigerSHARC platform. The main objective of this paper isto bring out overall signal processing flow from ADC to Tracking for a good number of satellites. Thesemethods were first developed in the Matlab and then real time implementation was done on TigerSHARCDSP platform running at 500MHz. The whole platform consists of RF portion, FPGA and TigerSHARC

DSP. The sampled one-bit data comes from GPS RF front-end module, which consists of single stagedown conversion followed by ADC section. The GPS signal is CDMA using direct sequence to bi-phasemodulate the carrier frequency. FFT based correlation is used for signal acquisition to determine the carrierfrequency and code phase for each of satellites. Acquisition is followed by Carrier Pull-in module, whichgives close carrier frequency in the tracking range. Acquisition to tracking transition includes the estimationof PRN Code shift over a period of time and the modeling of ADC sampling clock error. Time taken byAcquisition and Carrier Pull-in module is important for a real time scenario. For achieving real time tracking,the ADC sampling clock characteristics are found out and modeled. Tracking module consists of codetracking loop and carrier tracking loop. An efficient way of implementing a MAC operation suitable for early,late and prompt correlation on a digital signal processor is presented. This approach makes efficient use oflogical XOR instruction of the DSP. All the algorithms of GPS signal processing were integrated withNavigation processing module (satellite and user position computation) and are tested and validated usingSpirent communications 12 channel GPS simulator

Auditory Prostheses is an electronic device that partially replaces the functions of the human ear. Unlike ahearing aid, it does not make sound amplification or filters the noise signal but instead bypasses normalhearing operation to directly stimulate the auditory nerve with electric current allowing hearing impairedpersons to receive sound. Auditory Prostheses is an artificial replacement of damaged inner ear usingexternal body worn speech processor and internal receiver-stimulator for stimulating auditory nerve viaelectrode array that enables understanding the speech by brain. Speech processor receives an externalsound or speech and generates encoded speech data bits for transmission to receiver-stimulator.Development of the Digital Sound Processor for Auditory Prostheses (DSPMAP) is based on the ANALOGDEVICES Digital Signal Processor ADSP-2185 is described. The DALLS DS89c420 microcontroller is used

as data encoder to send speech information from speech processor to receiver-stimulator via RFtranscutaneous link. The system comprises a Digital Sound Processor, Microcontroller based DataEncoder, a Radio Frequency Transmitter using Amplitude Shift Keying (ASK), ASK receiver, Receiver-Stimulator, and an Electrode Array of six electrodes. Continuous Interleaved Sampling (CIS) speechprocessing algorithm is implemented for the sound processor. A multi-channel cochlear implant with sixelectrodes or simulated resistance array can be driven by the receiver-stimulator for testing itsperformance. The implementation aspects of CIS algorithm are validated using the test data of speechsamples. The results are presented using laboratory model of receiver-stimulator and simulated electroderesistance array with a high-speed data acquisition system.

The Network Processors (NP) are designed for a wide range of access and edge applications includingmulti service switches, routers and deep packet inspection. The NPs are fully programmable Processorswhich utilize the technological advancements such as Hyper Task Changing which enables them toperform number of simultaneous operations. This ensures full network performance and alsoaccommodates complex services such as security on a packet basis. In this paper, the NP has beenconfigured as a Router and the performance statistics of the NP under RSA algorithm has been assessed.Since Network Processor can be configured on different design mapping, Cryptography has been includedas part of Protocol Suite to provide security at line speed. It is well known that RSA is an implementation ofthe more general concept of Public key cryptography method for encrypting messages. Hence,Cryptography on packet basis has better performance and flexibility on a Network Processor.
