Abstract

        Based on the factor graph, a joint channel estimation and detection method is proposed for orthogonal frequency
division multiplexing (OFDM) systems employing multiple transmit and
receive antennas (MIMO). Using belief propagation, statistics of the fast varying MIMO multipath channel are utilized in estimating channel coefficients. By proper message scheduling and passing, the proposed receiver is effective for MIMO-OFDM system in fast fading frequency-selective channel.
