Abstract

In order to ensure the bit error rate and reduce the complexity simultaneously, in this paper, we propose a quasi-orthogonal space-time block code (QO-STBC) decoding algorithm based on pairwise-minimum mean square error (pairwise-MMSE). The complexity of the proposed algorithm has nearly linear complexity, lower than that of the pairwise algorithm. Meanwhile, the bit error rate of the proposed algorithm is close to that of the traditional pairwise decoding algorithm, better than that of the existing zero force (ZF) algorithm, MMSE algorithm and pairwise-zero force (pairwise-ZF) algorithm.
