摘　　要：提出了一种基于发送赋形的空间复用MIMO方案。该方案将空间复用多天线技术与智能天线的波束赋形技术相结合,兼具了两者的优势,能在传送多路数据的同时有效对抗干扰和噪声,大大提升系统的性能。该方案在相同仿真条件下比基于空间复用的VBLAST技术和波束赋形技术具有更低的误码率性能及更高的频谱效率。A spatial multiplexing MIMO scheme with beamforming was proposed. The proposed scheme combines spatial multiplexing and beamforming, which has the advantages of both techniques. It is able to transmit parallel data streams as well as combating interference and noise efficiently and improve the system performance significantly. The proposed scheme provides better BER performance and greater spectrum efficiency than VBLAST and beamforming techniques under the same simulation environment.
