摘要：
We propose a new decoding method for multi-user detection when space-time block codes are used at the transmitter. Specifically, we consider an arbitrary number of simultaneous co-channel users and present a decoding method to detect their symbols. Simulation results show that the proposed decoding method gives better performance when compared to existing methods. The extension of the method to 4-antenna transmit diversity schemes is discussed. The effect of the Rician factor of the channel on the system performance is analyzed. Simulation results indicate superior performance with the new decoding method for the 2 and 4-antenna systems.
