| Abstract: | 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. |
