The current prototype investigates a few basic techniques (such as synchronization, multiservice switching) which are primarily intended for mobile systems and can be extended to further applications (e.g., enhanced VSAT's). The baseline up-link includes a flexible mixture of SCPC and very low rate TDMA and the downlink is TDM, so that compatibility with ground cellular networks could be achieved eventually. These techniques are going to be validated by a comprehensive test-bed set-up and can evolve into field experiments.

We propose a theoretical model to compute the error probability in the case of a generic frequency-selective channel. Moreover, the proposed method is also extended to deal with nonuniform, i.e., wavelet, transceivers. The accuracy of the model is evaluated by means of computer simulations, using several types of filterbank transceivers. Systems based on cyclic prefix (CP) and zero padding (ZP) are considered to avoid interblock interference (IBI) in frequency-selective channels. The analytical results obtained with the proposed method allow us to quickly compare different systems, characterized by a different filterbank selectivity, as well as by different methods to combat IBI (ZP or CP).

The turbo-MUD receiver is based on the use of a linear MMSE detector in the first iteration and a parallel interference cancellation scheme in the successive ones. The inputs of the interference cancellator are both the detector outputs and the soft information from a bank of turbo decoders. The performance of the proposed receiver has been derived by means of computer simulations and applications of the density evolution theory: in particular, this technique permits to properly evaluate the number of MMSE iterations, simplifying the overall receiver design.

An advanced implementation architecture based on shared buffers at each input is studied. An important result is that the proposed switching fabric achieves optimum throughput-mean switching delay performance jointly with reduced buffering requirements and without having to resort to a faster switching fabric.

COST 252 Action starting from the results achieved within COST 227 Action and the related RACE II projects (e.g., MONET, SAINT and MBS) investigates the feasibility of such an evolutionary approach and contributes to the standardization phase of future generation systems.
