摘　　要：文章提出了一种基于准正交空时编码的波束形成系统的接收端改进模式,对接收端信号进行选择性接收,从而提高了系统性能。在文章提出的接收模式中,接收端把接收信号分成两组进行接收,通过这种方式可以减少来自邻近信号的干扰。仿真结果表明在完美信道估计下提出的方法能够很好改善系统性能。In this paper, an improved selective receiver scheme of beamforming based on QOSTBC, is proposed, thus making a selective receive on signals to improve performance of the system. In the proposed scheme, the received signals is divided into two groups. By this way, the interference from the neighboring signals is reduced. The simulation results indicate that the proposed scheme can provide improved performance under perfect channel estimation.
