To carry out simple linear decoding, it is usually assumed in space-frequency block coded orthogonal frequency division multiplexing (SFBC-OFDM) systems that the channel frequency responses between sub-carriers remain constant within a block length [1]. However, this assumption becomes unreliable when the system operates in a severe multipath environment. The conventional linear decoder [1] gives rise to inter-channel interference (ICI) due to variations of channel frequency response between sub-carriers. In this paper, we propose a turbo-based interference cancellation scheme to mitigate this effect. While the implementation complexity is higher than for conventional detection, the proposed scheme can effectively eliminate ICI, and exploit the increased diversity available in channels with long delay profile.
