In this paper, the proposed quasi-orthogonal space time block code (QO-STBC) cooperative communications with relay selection is investigated. The proposed QO-STBC coded cooperative communications provide a good relay selection strategy such that the diversity of four is achieved. In addition, a code rate of the proposed scheme is twice the ordinary cooperative communications. Computer simulation results show a significant probability of error performance improvement of about 4 dB over the conventional decode and forward protocol.
