Abstract: A popular technique for high data rate wireless transmission is OFDM. To increase the diversity gain and/or to enhance the system capacity, in practice, OFDM may be used in combination with antenna arrays at the transmitter and receiver to form a multiple-input multiple-output (MIMO) system. In this paper, an iterative multiuser receiver structure for space-time block coded MIMO OFDM scheme is exploited over slow fading channels. We utilize iterative detection based on minimum mean square error updated with decision feedback (MMSE-DF). The symbols are estimated in iterative process by updating extrinsic information to develop log-likelihood ratios (LLRs). Simulation results indicate that the scheme is proposed for the considered scenario and the performance over classical linear MMSE estimator.
