摘　　要：研究了分布式多输入多输出系统的信道容量,对信道非满秩情况进行讨论,分析了天线选择对于信道容量的影响。对信道容量的仿真表明:在分布式MIMO系统中对发射天线进行选择可以提高信道容量。同时选择天线可以减小系统的复杂度和硬件成本。The channel capacity in distributed MIMO system is first analyzed, then the channel without full rank is studied, and the effect on channel capacity is calculated with antenna selection. Through the simulation of the channel capacity in distributed MIMO system, it was found that the channel capacity is enhanced by antenna selection, and the antenna selection reduces the system complexity and hardware cost.
