Abstract	In this paper, a new type hybrid automatic-repeat-request (HARQ) scheme based on different space-time codes is proposed and evaluated. The new scheme is divided into three major steps which are V-BLAST processing, TSTC processing and STBC processing. In order to benefit from spatial diversity, the proposed method transfer the next line of data matrix and joint-decode them, not the same as simply signal retransfer. And if channel is in good condition, that the proposed method gets spatial multiplexing for retransfer hardly occur. The proposed method takes advantage of V-BLAST, TSTC and STBC, moreover, it is a HARQ scheme that can improve transmit rate and resistance of interference at same time. Theory and simulation show this proposed method have higher throughput in most SNR regions and the result is also satisfying.
