Exploiting linear block codes for blind co-channel interference reduction in TDMA based wireless communication systems

In this paper, we present a novel array processing technique for co-channel interference reduction for TDMA based mobile satellite communication systems using linear block codes. This technique combines least squares projection with syndrome detection (LSPSD) to compute the optimum multi-antenna linear receiver for a signal of interest (SOI) encoded with a linear block coding scheme. The algorithm is shown to reduce co-channel interference and to improve bit error rate performance. Further, we show that the algorithm achieves SNR improvement by coherently adding multipath components of the SOI.
