Paper abstract
-----
This paper studies a space-time generalization of decorrelating RAKE receiver recently proposed by Liu and Li for blind multiuser detection of direct sequence code division multiple access (DS-CDMA) signals under frequency selective fading channel. Multiple receiving antennas are employed to further enhance the performance of the DRAKE receiver through diversity combining. Simulations show that the proposed space-time DRAKE (ST-DRAKE) receiver performs significantly better than the temporal-only DRAKE receiver and its performance is close to that of the MMSE receiver. The use of multistage Wiener filter to reduce the complexity of the ST-DRAKE is also studied.
