| 摘 要： | 首先推导了分布式MIMO点对点链路遍历信道容量的近似表达式或理论下界,然后给出小区平均遍历容量的表达式.在此基础上,研究D-MIMO与C-MIMO系统分别在BT和ST两种天线选择机制下的平均遍历容量.最后通过仿真,证明了所推导理论表达式的正确性,同时比较了两种MIMO系统的信道容量.

| Abstract: | In this paper, firstly, the approximate expression and theoretical lower bound of the ergodic capacity of point to point channel are deduced, secondly, the expression of the average ergodic capacity is deduced. On this basis, it describes the average ergodic capacity of the C-MIMO and D-MIMO cellular systems in BT and ST antenna selection mechanisms. Through the theoretical value is compared with the Monte-Carlo simulation value, the correctness of the theoretical expression is proved, at the same time, the channel capacity of the two MIMO systems is compared. |
