Truncated maximal ratio combining for iterative multiuser decoding

In this paper, the concept of information combining is investigated for iterative multiuser decoding. This is done by applying recursive maximal ratio combining (MRC) over iterations to interference cancellation based multiuser detectors. Here, we show that combining over all iterations may not be appropriate as correlations build up. Numerical results show that applying MRC only over the first few iterations can improve the bit error rate performance with only a modest increase in complexity, as compared to no combining.
