Programme Element: ARTES 5.1
Reference nr.: 13.1TT.48
Planned Tender Issue: quarter 4, 2013
Objective: Design, develop and test key prototype elements for advanced access techniques. Both the terminal transmitter and the GW receiver will be prototyped and tested.
Targeted Improvements: The target prototype techniques have the potential (depending on the particular network parameters) to improve the throughput by more than 100% and/or significantly reducing the end-to-end transmission latency.
As of today, the satellite communications in the return link use standards similar to DVB-RCS2. The more recent specifications are being prototyping in some on-going ESA projects. In case of DVB-RCS2, the CRSDA protocol still lacks a really representative prototype, in particular for what concerns the multi-frequency feature.
Very advanced techniques have now recently become available for the return link of SATCOM systems with the potential to significantly improve the performance of the access schemes. These include time-frequency packing, multi-user detection with advanced synchronization schemes, multi-frequency advanced random access schemes, advanced diversity techniques.
Prototyping of the new return-link advanced techniques on a single HW/SW platform would allow an assessment of the complexity of such techniques. Testing with a realistic channel simulator would allow an assessment of their performance for next generation SATCOM systems.
The work will be organised in two phases.
In the first 6 months the consolidation of the new techniques at algorithmic level would be carried out, together with the reference system scenario selection for testing the techniques. In addition, the architectural design of the prototypes would be carried out.
In the remaining 12 months, the activity would be focused on the development of a proof of concept for both the terminal transmitter and the GW receiver. A realistic channel emulator may be provided by the Agency to support the activity. Prototyping can be carried out on DSP/GPU-based fast prototyping boards to reduce the schedule and cost of the activity..
