摘要
MIMO系统可以在不增加带宽的情况下成倍地提高通信系统的容量和频谱利用率,是新一代移动通信系统的关键技术。在简要介绍MIMO系统的工作原理及容量公式后,对不同信噪比、不同发射、接收天线数目情况下的系统容量进行了仿真分析。
MIMO system can enhance the capacity and spectral efficiency of telecommunication system without increasing bandwidth,which is a key technology of the next generation mobile telecommunication.In this paper the principle and the formula of channel capacity of MIMO systems are introduced,and the channel capacity is simulated with different SNR and different antenna number.
