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.
