Abstract
An iterative noncoherent receiver that does not exploit channel statistics is proposed for the detection of differential space-time block codes (DSTBCs) in fast-fading channels. For robustness to channel variation, it employs an iterative architecture incorporating <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">a priori</i> information from a channel decoder in the Viterbi detection. Computer simulation shows that the performance of this iterative scheme is comparable with that of ideal coherent detection as the number of iterations increases.
