The project is aimed at the identification, analysis and optimisation of adaptive Fading Mitigation Techniques (FMT) together with the corresponding protocols, signalling information and formats in order to significantly increase the efficiency of future broadband DVB-RCS based satellite systems as compared to current systems.
As a consequence, this activity is intended to study and propose appropriate FM techniques including physical layer, signalling, MAC protocols and resource allocation (RA) algorithms for the different link types of a transparent as well as regenerative satellite system scenario. This includes the different services with different Quality of Service (Q.o.S.) requirements in order to demonstrate the achievable system efficiency under realistic conditions.
The demonstration/assessment needs to take into account physical layer impairments, such as channel estimation errors, synchronisation performance, impact of non-linearity, interference, limitations concerning the order of modulation and FEC coding type and rate, as well as traffic, required signalling overhead, imperfections of the resource allocation or induced latency. The performance of the FMT solutions for the various reference scenarios will be demonstrated/assessed through detailed simulations.
