摘要 介绍在多输入多输出(MIMO)系统中,以最大化信噪比(SNR)为准则,结合收发波束成形的设计方法;并在此基础上,比较收发波束成形的技术与基于Alamouti方案的空时分组码方案的误比特性能。通过计算机仿真,证明收发波束成形技术对于降低接收误码率的重要作用。 This paper presents the design of beamforming on the maximum signal noise ratio （SNR） criterion in MIMO systems with channel state information （CSI） feedback. And based on this, the comparison of BER between beamforming and Alamouti STBC is made. Simulation results demonstrate the important role of beamforming to reduce the error rate of MIMO systems.
