We study the iterative soft interference cancellation-minimum mean square error filtering (ISIC-MMSE) detector with estimated channel state information (CSI) for bit-interleaved coded modulation (BICM) spatial multiplexing multiple input multiple output (SM-MIMO) systems. By considering the channel estimation errors in all detection modules, we propose a modified ISIC-MMSE detector which considerably outperforms the conventional ISIC-MMSE detector in terms of performance and transmission rate with only moderate complexity increase.
