A new quasi-orthogonal space-time block code （QO-STBC） based on ABBA code with lower decoding complexity and higher bit error statistics （BER） performance was proposed by U. Park recently, which can obtain full transmission rate and full diversity. In this article, the authors proposed an improved U. Park scheme based on rotational ABBA code. For eliminating the interference terms resulting from neighboring signals during signal detection, two different matrixes are used. And independent decoding can be realized when maximum-likelihood decoding at the receiver is used. Simulation results demonstrate that the BER performance is improved dramatically without increasing the decoding complexity compared with U. Park scheme.
