摘要

本文对同址天线系统(CAS)和分布式天线系统(DAS)的MIMO信道容量进行了比较研究。在DAS中，我们考虑了包含瑞利衰落、对数正态阴影衰落和路径损失的信道模型。我们发现不同的功率分配方案和不同的移动设备位置对MIMO-DAS的信道容量增益有显著影响，并且MIMO-DAS比传统的MIMO-CAS具有更大的容量增益，这在我们的仿真中得到了证明。

Comparison of channel capacity for MIMO-DAS versus MIMO-CAS

This paper proposes a comparative study of MIMO channel capacity for both co-located antenna system (CAS) and distributed antenna system (DAS). In DAS we consider the channel model compassing the Rayleigh fading, log-normal shadowing fading and path loss. We find that different power allocation schemes and different locations of the mobile affect the channel capacity gain of MIMO-DAS significantly, and MIMO-DAS offers large capacity gain over the traditional MIMO-CAS, which is demonstrated in our simulations.
