We present results on multipath channel estimation and detection for space-time coded systems used in conjunction with orthogonal frequency-division multiplexing (OFDM). An expectation-maximization (EM) based algorithm is introduced and is shown to be more robust to multipath channel delay profile variations and can be implemented more efficiently compared to a recently proposed alternative algorithm at similar or better performance
