摘要
Like differential phase shift keying (DPSK), a differential space-time block code has recursive encoding structure and then, when it is concatenated serially with a channel code, additional coding gain from the concatenation is obtained. To take the additional gain, a recent research has introduced serial concatenation of the differential space-time block code and a channel code, and its sub-optimal iterative receiver. The receiver consists of two APP decoders, which not only has considerable computational complexity, but also Is not suitable especially for the differential space-time block code. This paper proposes a simpler, more suitable decoder for the differential space-time block code in the serial concatenation than the APP decoder. The core idea of the proposed decoder is to employ a maximum likelihood decoding method. With low complexity, the receiver with the proposed decoder shows the performance almost identical to the conventional one's in a time-correlated fading channel.
