The use of multiple antennas in combination with advanced detection techniques, such as turbo equalization is an effective means for a communication system to provide high quality and high data rate services. Alamouti's space-time block code (STBC) with two transmit antennas and one or two receive antennas over frequency selective multiple-input, multiple-output (MIMO) channel is considered in this paper. The maximum likelihood detection for the studied system is investigated and shown to be prohibitive for implementation. In order to reduce the complexity, we propose a turbo equalization scheme based on the approximate maximum likelihood (AML) algorithm. The proposed scheme is shown to provide large performance gains compared to the original Alamouti algorithm and the conventional linear minimum mean square error (MMSE) based turbo equalization for the STBC coded systems.
