Problem (1)

Communication methods traditionally used in aeronautical environment:

• Voice analog communications,– VHF, UHF and HF bands (AM);

• Telemetry digital communications,– L, S, C bands (CPFSK, SOQPSK).

• …

Problem (2)

Some Unmanned Aircraft (UA) applications (e.g. remotely piloting) need communication data-

links with specific requirements in terms of• data-rate,• reliability,• security. Modulation and coding techniques

traditionally used (e.g. for telemetry) are not

suitable to transmit at very high data-rates

Research Activity (1)

The adoption of• orthogonal frequency-division multiplexing

(OFDM),• possibly coupled with multiple-input multiple-

output (MIMO) antenna configuration,is viable to obtain the objectives.

Ivan Iudice 7

Research Activity (2)

Channel models of UA environment are needed to correctly implement MIMO-OFDM technologies and design robust modulation and coding schemes for achieving high reliability.• Statistical models: they are well motivated when the time

varying path delays arise due to the large number of scatterers.

• Deterministic Basis Expansion Models (BEMs): they are more useful when multipath is caused by a few strong reflectors and path delays exhibit variation due to the kinematics of the mobiles.

Developments

• I started formalizing a MIMO-OFDM model that should involve all issues relevant to the UA context.

Developments

• I started formalizing a MIMO-OFDM model that should involve all issues relevant to the UA context.

• The BEMs are been analyzed and applied to UA context.

Next years: specific objects

• MIMO-OFDM– Derived model will be used to analytically evaluate the expected

performance, and then simulate a possible implementation.– MIMO-OFDM techniques will be implemented in a reconfigurable

data-link (SDR paradigm) and tested on flying laboratory at CIRA.• BEMs

– I will verify whether these models are suitable for aeronautical environments, specifically in UA applications (using both data collected from literature or direct measurements at CIRA).
