摘　　要：由于发射天线数目超过2的Alamouti正交分组码(STBC)编码速率小于1,不能保证通信数据的全速率传输。本文在此基础上提出一种新的准正交空时分组码的编码方法,在确保分集增益最大化的前提下,信号传输达到全速率。If there are more than two transmit antennas in a communication system, the code rate of the space-time block codes （STBC） would be less than one. That makes transmit data to be fed at a situation of deposit. We can introduce the idea of quasi-orthogonal codes, to enhance the code rate to a higher level. In this paper, we propose an improved space-time block code based on quasi-orthogonal design,which can ensurn data transmition at a full rate on high diversity gain.
