The information capacity of wireless communication systems may be increased dramatically by employing multiple transmit and receive antennas. In this paper, we consider multiuser wireless communication system employing multiple transmit and receive antennas. We estimate jointly channel and symbols user-wise by maximum likelihood approach (ML) approach. Two models are considered for the symbols of the interferers, corresponding to Gaussian and discrete priors. In the latter case, in which the finite alphabet gets exploited for the MAI symbols, a simplification for the posterior MAI symbol probabilities is introduced based on mean field theory.
