  Abstract

.In this paper, a low complexity blind space-time multiuser detector is proposed. The conventional scheme used MOE(minimum output energy) detectors to suppress multiuser interference and MRC(maximum ratio combiner) to obtain spatial and temproal diversity. The proposed scheme uses MV(minimum variance) detectors and MRC. It is shown that one MV detector has the same performance as many MOE detectors as the number of multipath with MRC(Maximum Ratio Combiner). From this fact, we show that the proposed blind space-time multiuser detector has lower complexity than conventional one. And through the computer simulation, we show that the proposed blind space-time multiuser detector has better performance than the conventional one.
