Claim:
1. A method of decoding spatially multiplexed signals received by a wireless device, the method comprising: receiving, using a plurality of receive chains, spatially multiplexed signals including a plurality of symbols from a transmitting device; deriving, using one or more processing devices, an estimated channel matrix H from the plurality of received symbols; decomposing, using the one or more processing devices, the estimated channel matrix H into first and second unitary matrices Q applying, using the one or more processing devices, a first M-algorithm process to a bottom set of N applying, using the one or more processing devices, a second M-algorithm process to a top set of N performing, using the one or more processing devices, a distance determination over M*M candidates by combining the first and second sets of M candidates from the top set and the bottom set, wherein M identifies a number of candidate neighbors; and obtaining, using the one or more processing devices, a candidate from among the M*M candidates having a global minimum distance to select a final decoded symbol vector identifying a given one of the plurality of received symbols.
