Abstract :
Multiple reception antenna assisted space division multiple access (SDMA) techniques designed for wireless OFDM systems have recently drawn wide interest. These techniques facilitate the implementation of effective multiuser detection algorithms at the receiver, such as minimum mean-square error (MMSE) detection, successive interference cancellation (SIC), parallel interference cancellation (PIC) or maximum likelihood (ML) detection. We investigate the performance of the MMSE and PIC detection techniques in the context of a Walsh-Hadamard spreading assisted SDMA OFDM system
