In this paper, we propose an efficient rate one quasi-orthogonal space-time block code for three antenna system. In order to compensate the performance degradation due to quasi-orthogonal scheme, in this proposed scheme, we incorporate a selective receiver for decoding. The receiver divides the received signals into two groups, and two receiving antennas alternatively operate to receive the divided...
In this letter, we propose a quasi-orthogonal spacetime block coding (QO-STBC) scheme with maximum likelihood (ML) decoding via simple linear detection. A conventional QOSTBC scheme can achieve the full rate, but at the cost of decoding complexity and diversity gain. These disadvantages of the conventional QO-STBC scheme are mainly a result of interference terms in the detection matrix. In this letter,...
