Diversity analysis of MIMO wireless system in Rayleigh fading

针对多输入多输出(MIMO)无线通信系统提高系统性能的同时增加了系统的复杂度,提出了基于最大特征值传输的分集解决方案,在天线数量一定的情况下最大可能的提高系统的分集增益。对单输入多输出和多输入多输出的情况进行了数学分析,推导出了系统性能的变化范围,并且对分析的结果进行了数值仿真。

Using multiple antennas at both the transmitter and receiver can get diversity gain and beamforming gain in wireless systems, but it increases the system complexity and cost at the same time. A maximum eigenvalue transmission solution is presented for MIMO diversity in Rayleigh fading channel, a mathematical analysis is given to deal with the performance variation, and a numerical simulation is provided for performance comparisons in this paper.
