中文摘要：
提出了一种基于2×2天线阵列的BLAST与STBC的结合算法,在初始传输的时候使用BLAST来提高系统容量,如果出错则重传的信号和初始信号结合为STBC来获得高的分集增益.该算法相对于BALST算法有更低的误码率,相对于STBC算法有更高的传输速率,因此具有良好的性能和优越的鲁棒性.仿真结果证明,通过少量的额外带宽为代价换取了性能的很大提升.
英文摘要：
This paper present a method, base on 2×2 antenna array, which combined by BLAST and STBC. At first, system transmit signal as BLAST to get high output. If failed, system resend signal that can combine with first signal to form STBC. STBC have very good performance to resist interference, it can improve robust of system greatly. The proposed scheme combine advantage of BLAST and STBC, it can provide high output and good robust at same time. Theory and simulation shows the proposed method have very good performance, but it only need little additional bandwidth to feed back error information, the spending of bandwidth is worthy.
