同时得出了系统中断概率的具体表达式及其误码率的近似值.在此基础上分析了Keyhole MIMO信道下的天线选择问题.最后进行了仿真

其结果与理论分析一致.研究表明

在Keyhole MIMO信道中

采用天线选择仍然能够获得与全复杂系统相同的分集增益.

Abstract

We present a comprehensive analysis for the capacity and bit-error rate (BER) performance of orthogonal space-time block codes (STBCs) over Nakagami fading channels in the presence of keyholes of in multiple-input multiple-output (MIMO).We first derive a tight lower capacity bound.We also present the exact expression for the outage probability and an approximated BER formula.On this basis

we analyze the antenna selection problem over keyhole MIMO channels.Finally numerical results are presented to verify our analysis.It is shown that the diversity order

with antenna selection

is maintained as that of the full complexity system.
