摘　　要：针对MIMO系统空时分组码复正交设计和全速率传输的矛盾问题,通过牺牲部分正交性来换取全速率,使其在形式上接近于正交矩阵,并按一定规则设计使得空时分组编码能够保证编码速率为1从而实现全速率传输。最后通过仿真验证了所提方案的优越性能。In view of the MIMO system space-time contradiction problem code complex orthogonal design and full rate transmission,in exchange for full rate by sacrificing partial orthogonality, which is in the form similar to the orthogonal matrix,and according to certain rules of design so that the time block coding can ensure that the coding rate is 1 in order to achieve full rate transmission.The simulation shows that the superior performance of scheme.
