In a method of demodulating a signal transmitted via a multiple input multiple output (MIMO) communication channel, a data symbol vector is received at a communication device, the data vector comprising a plurality of data symbols that are received via a plurality of antennas. The received data symbol vector corresponds to a transmitted data symbol vector comprising a plurality of transmitted data symbols. A plurality of candidate vectors for the transmitted data symbol vector are generated at the communication device using a plurality of non-maximum likelihood detection techniques. One candidate vector is selected from the plurality of candidate vectors at the communication device using a maximum likelihood technique.
