Abstract
Disclosed is a signal detection method for a receiver of a Multiple-Input Multiple-Output (MIMO) communication system having nand n(where nis greater than or equal to n) transmission and reception antennas, respectively, and an n×nchannel matrix. The signal detection method includes selecting a plurality of sub-channel matrices having smaller dimensions than the n×nchannel matrix, estimating transmission symbols received from corresponding transmission antennas using a maximum likelihood decoding method with respect to a received signal corresponding to each of the sub-channel matrices, estimating transmission symbols received from the remaining transmission antenna(s) using the estimated transmission symbols, temporarily storing a candidate symbol set composed of the estimated transmission symbols, and comparing candidate symbol sets corresponding to all the sub-channel matrices and determining the smallest candidate symbol set as a transmission symbol set.
