For multiple-input multiple-output (MIMO) bit-interleaved coded modulation (BICM) systems over block fading channels, a computationally efficient iterative receiver is investigated with the expectation-maximization (EM)-based MIMO channel estimation. Replacing a joint detector and decoder by an iterative detector and decoder, the resulting receiver becomes a doubly iterative receiver. To reduce the complexity of the MIMO detection, a simplified minimum mean-square error (MMSE) combining with soft (interference) cancellation (SC) is considered. The relation to the MMSE decision feedback detector (DFD) is also addressed. © 2006 IEEE.
