摘要

考虑指数相关性，将多用户多输入多输出(MIMO)系统的中断概率和平均误码率与发射天线选择最大比组合(TAS/MRC)相结合。当天线在接收器中以线性阵列放置时，可以观察到指数相关性。导出了二元调制的中断概率和ABER的封闭解析表达式。研究了中断概率与ABER在不同分集阶数下的相关性。最后，通过蒙特卡罗仿真验证了所得解析表达式的正确性。

Performance of multiuser TAS/MRC-MIMO systems over Rayleigh fading channels with exponential correlation

In this paper, the outage probability and average bit error rate of a multiuser, multiple input multiple output (MIMO) systems has been incorporated with transmit antenna selection maximal ratio combining (TAS/MRC) over Rayleigh fading channels considering exponential correlation. Exponential correlation is observed when antennas are placed in a linear array in a receiver. A closed form analytical expressions for the outage probability and the ABER for binary modulations have been derived. Outage probability and ABER have been studied for various levels of correlation with different level of diversity order. Finally, obtained analytical expressions have been validated by Monte-Carlo simulation.
