Abstract
We investigate an iterative receiver structure per- forming joint symbol detection and decoding to sup- press the strong interference in multiple input multiple output (MIMO) systems. A linear minimum mean- squared error (MMSE) detector is compared with a simplie d approach. Existing approaches for related scenarios are modie d and extended to t to a gen- eralized MIMO transmitter structure such that the de- veloped detectors are applicable to many known MIMO systems. Simulation results show that the proposed it- erative receivers achieve large gains over standard so- lutions. Interestingly, feeding back the entire a pos- teriori information from the decoder to the detector outperforms the common approach of feeding back ex- trinsic information.Keywords
