Iterative multiuser detection performance evaluation on a satellite multibeam coverage

This paper deals with the use of non-linear multiuser detection techniques to mitigate co-channel interference on the reverse link of multibeam satellite systems. The considered system is inspired by the DVB-RCS standard, with the use of convolutional coding. The algorithms consist of iterative parallel interference cancellation scheme with semi-blind channel estimation. We propose a simple approach for statistical evaluation on a multibeam coverage, and present results obtained on a coverage designed on a digital Ka-band focal array feed reflector antenna.
