Spatially Multiplexed Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (SM-MIMO-OFDM) technology is envisaged to raise transmission capacity over the wireless channels up to 10bps/Hz, allowing for ubiquitous access to multimedia services in the 4G cellular networks. Future transceivers will incorporate MIMO antenna arrays of larger dimensions than those specified in the presently existing standards (with maximum 4 antennas). Thus, a crucial part of the cost-effective system design will deal with the low-complexity detector architecture, providing for optimal or suboptimal performance. In this paper, the authors propose such a detection technique and examine its error rate performance in the conditions of the dynamic channel model.
