摘　　要：将智能天线赋形技术引入MIMO系统。根据赋形技术和MIMO的分集复用技术的特点,分析比较了这2种策略的适宜运用条件。通过仿真对不同环境条件下MIMO系统中采用分集复用技术和智能天线赋形技术的系统容量进行比较,指出了为达到最优系统性能,不同环境下应采用的不同天线。In this paper,the authors introduce the smart antenna beamforming into the MIMO system. According to the characteristics of beamforming and diversity,the authors analyse the application condition of the two techniques. At last, through simulation,the authors further comparision of the MIMO capacity in diversity and beamforming is made and the result shows that various technique should be used in different condition to get the better performance.
