Abstract
A space-time multiuser detector simultaneously reduces multiple access interference (MAI) and multipath channel distortion (MCD) that are disadvantages of mobile communication systems. The space-time multiuser detector includes a plurality of receiving antennas; a channel estimator which estimates signals received via the receiving antennas; a space-time diversity decoder which performs space-time decoding with respect to the signals provided from the channel estimator and performs diversity combination; a signal aligner which aligns the signals provided from the space-time diversity decoder; and a successive interference cancellation detector which generates an interference signal from the signals that are provided from the signal aligner one by one in sequence, and removes the interference signal from the received original signals.
