| 摘 要： | 分布式MIMO系统结合了点对点MIMO信道与分布式天线系统两者的特点，能改善链路的质量，提高覆盖面积。本文提出了一种包含路径损耗、阴影衰落与小尺度衰落的分布式MIMO信道模型，分析推导了采用该模型时的分布式MIMO信道容量。通过计算机仿真，研究分析了阴影衰落、Rice信道因子K等因素对分布式MIMO上行信道容量的影响，得出了分布式MIMO信道容量空间分布的特点。

| Abstract: | A Distributed Multiple Input Multiple Output (MIMO) system combining the characteristics of traditional MIMO systems and distributed antenna systems is proposed to improve the link quality and coverage. At the beginning of this paper, a distributed MIMO channel model taking path loss, shadow fading and small scale fading into account is established. Then the formula concerning the capacity of distributed MIMO channels is derived. The impact of shadowing and Rice channel factor K on the uplink capacity of proposed model are thoroughly investigated through Monte Carlo simulations as to obtain the characteristics of capacity space distribution of distributed MIMO channels. |
