| 1. A space-time multiuser detector having multiple transmitting and receiving antenna, comprising:
a plurality of receiving antennas which receive a corresponding plurality of original signals;
a plurality of channel estimators which estimate channels of the plurality of original signals;
a space-time diversity decoder which performs space-time decoding with respect to the plurality of original signals using
the characteristics of the estimated channels and performs diversity combination to generate decoded signals;
signal aligner which aligns the decoded signals according to a predetermined reference to generate aligned signals; and
a successive interference cancellation detector which receives the aligned signals and generates one or more interference
signal, and removes the interference signals from the aligned signals.
