Diversity Interference Cancellation Using Prefiltering and Reduced-State MIMO Equalization

We consider a joint detection approach for cancellation of co--channel interference in time--division multiple access (TDMA) mobile communications systems like GSM/EDGE (Enhanced Data Rates for GSM Evolution). Concepts from reduced--state equalization of frequency--selective multiple-- input multiple--output (MIMO) channels are applied together with prefiltering. A novel efficient prefilter computation algorithm is presented. Simulation results demonstrate the high performance of the proposed receiver for GSM/EDGE applications
