Abstract: An adaptive receiver for Space-time block coded (STBC) multiuser systems and an iterative interference cancellation (IIC) receiver for STBC multirate multiuser systems are presented. The adaptive receiver is proposed based on least square error - recursive least square to suppress the interference from synchronous co-channel users without any explicit knowledge of channel state information (CSI) and interferer. Furthermore, the proposed adaptive receiver has less computational complexity than the minimum mean square error (MMSE) receiver and BER performs better than the differential space-time coding scheme proposed, where CSI is not needed at the receiver. The proposed IIC receiver is based on MMSE interference cancellation and maximum likelihood detection. The BER performance of the proposed IIC receiver is better than the conventional non-iterative MMSE scheme. In addition, the proposed scheme performs well not only in multirate multiuser systems but also in equal rate multiuser systems. As expected, the performance margin diminishes with number of iterations.
