Orthogonal frequency division multiplexing (OFDM) significantly reduces receiver complexity in wireless systems with multipath propagation and therefore has recently been proposed for use in wireless broadband multi-antenna (MIMO) systems. The performance of the maximum likelihood (ML) detector in MIMO-OFDM system is optimal, however, its complexity is prohibitive. A number of other detectors, both linear and non-linear, may offer substantially lower complexity, however, their performance is… CONTINUE READING
