  We present the results of the performance evaluation of polarization-time
coding and soft interference cancellation in multi-beam satellite systems
affected by co-channel interference in realistic setups. The standard of
Broadband Global Area Network service (BGAN) has been considered as reference
for the physical layer and realistic interference and channel models have been
adopted. The work has been carried out in the framework of the Next Generation
Waveform for Increased Spectral Efficiency (NGWISE) project founded by the
European Space Agency (ESA).
