Abstract :
The performance of the satellite communication system is limited by cochannel interference and multipath fading. In the present work, an iterative MMSE interference suppression in encoded TDMA satellite systems is proposed. Diversity of received signals at different hubs is assumed available and used to enable decoding of cochannel signals. The decoder outputs are fed back to help the cochannel interference suppression by employing a MMSE-base scheme. This process iterates as the decoder outputs converge to the transmitted symbols. A similar idea is also used to estimate channel response
