Course Facts• Credits: 12.• Grade: ECTS. A-F.• Group work.• Number of students per group

4-7 : Real-time based projects (DSP or Ubuntu)2-4 : USRP based projects.

• You choose among a set of “eligible” projects.• We form groups and assign a leader.• One Project assistant per group.• Course responsible: Per Zetterberg.• Prototype responsible: You!• Goals and time-table are specified, how to achieve this

is up to the team.

Real-time based projects

• Real-time processing on DSP board or Ubuntu PC.• Receiving data from sensors (e.g. A/D converters)

transmitting data on actuators (e.g. D/A converters).• Presentation on of results on PC.• The signal processing in real-time is one of the major

challenges due to real-time and memory constraints.

Group member roles:• DSP programmer.• PC programmer.• Matlab/theory developer.• Group leader.

4-6 students per group

5

USRP based projects

• USRP = Universal Software Radio Peripheral• Used to transmit and receive wideband (4-8MHz)

signals over real radio transmitters and receivers.• Matlab interface to download and upload I&Q samples.• The signals are distorted by real-world RF-impairments

(non-linearities,phase-noise, frequency offset).• Developing and analyzing algorithms under real-world

distortions is one the main challenges.• All processing in matlab.

2-4 students per group

6

Areas groups will work with• Algorithms (Matlab).• Project management.• Reports (Word or LaTeX)• Posters (PowerPoint or Adobe Illustrator)• Web-pages.• Oral presentation (PowerPoint)• Setting up experiments, connecting cables.• Integrating.• Debugging, debugging, debugging.

• DSP programming (CCS)• PC-programming (matlab-GUI or gcc-realtime)• Radio experiments.

Some will work with

7

Requirements• Working Prototype.• Project report.• Presentation and demo.• Poster.• archive.• Project plan.• Progress reports.• Mid-term evaluation

- DSP assignment (only DSP groups)- Matlab prototype (DSP groups)- Preliminary results

• Updated www-site.• Signed-off checklist (return equipment and literature).• Individual Reflective diary. Sent every week.

New this year!

Group work

• One group member is group leader.• Several tasks has to solved at the same time.• Group members will have to specialize in different

areas.• Project plan.• Weekly meetings and reports.• Examination is individual so every member has to

contribute proportionally.

Introduced 2008: Grades

“If the prototype is successful, the final-report is well written and contains adequate analysis and all the other deliverables are in good shape then all members who have made significant contributions will receive the highest grade. If this is not the case, the achievements of the individual group members will be scrutinized. This can be done by examining the progress-reports and other documents produced and from observations done during the course of the project”

1/4 (seven in all).• Mid-term evaluation 26/4.• Final report 27/5.• Poster, prototype archive 28/5, 8.00. • Grand final (oral presentation, demos) 28/5.

Check, are these dates OK ?

12

What would be your advice to a student who chooses this course next year ?• Don’t choose another course at the same period. Start really early with

everything.• Start working from the beginning• Work hard in the beginning and try to ease up in the end• Work hard in the beginning of the project• Start working from the first day, and don’t take more than a week off,

during the Easter• Choose it, but take it alone, with nothing else.• Work work work.• Take the course if you like to work hard.• Start early. Implement on DSP asap.• Don’t read other courses in parallel• Take it!

14

Project #1-3:802.11-like OFDM physical layer• Use the modulation scheme of the day : OFDM.

• Transmit/receive with a real IEEE802.11 transceiver. Learn to cope with real-world distortions.

• Specialize in 1) channel estimation 2) coding (convolution, turbo or LDPC) 3) inter-carrier interference rejection.

15

Project #4: Hierarchical Modulation

• How to multiplex data streams in a simple way?

• Broadcast to multiple receivers

• Hierarchical Modulation

• Multiple Access Channel

16

Project #5: Packet-Radio

•Three stations with DSP-board and radio transceiver (walkie-talkie).

•Send data between all the stations.

•Implement random access protocol (ALOHA, CSMA and CSMA-CD) to share the wireless channel.

•Measure the performance.

17

Project #6: Wireless Network Coding

• Network coding new field of information theory.

• Nodes in the network combine flows to utilize capacity better.

•In this project, a three node systems with network coding is implemented in real-time on DSP, with emulated fading channels.
