摘要

本文分析并优化了下行多小区多用户分布式多输入多输出(MIMO)系统的遍历容量。我们首先利用近似的伽玛分布推导出系统的遍历容量。为了使系统容量最大化，提出了一个关于RAU (remote access unit)天线数量和用户数量的优化问题。然后提出了一种迭代算法来获得RAU天线和用户的优化配置。仿真结果表明，该算法能够获得RAU天线和可支持用户的最优配置，使系统遍历容量最大化。

Performance analysis and optimization for downlink distributed MIMO systems

In this paper, we analyze and optimize the ergodic capacity for a downlink multi-cell multi-user distributed multiple input multiple output (MIMO) system. We first derive the system ergodic capacity by using the approximated Gamma distribution. In order to maximize the system capacity, an optimization problem with respect to the number of remote access unit (RAU) antennas and the number of users is formulated. Then an iteration algorithm is proposed to obtain the optimization configuration of RAU antennas and users. Our simulation results show that the proposed algorithm can obtain the optimal configuration of RAU antennas and supportable users to maximize the system ergodic capacity.
