【摘要】 以顺序统计量分析Rayleigh平坦衰落MIMO信道矩阵各向量能量的分布特征,给出其各阶矩公式以及列(行)数为1和2时行(列)向量的能量期望值的简洁表达式,并由此推导出信道矩阵的单边维数趋于无穷时行和列向量能量期望值的上下界。最后讨论了上述分析结果在MIMO系统的天线选择和分集增益计算方面的应用。更多还原

【Abstract】 The authors discuss the statistical distributions of multiple-input multiple-output (MIMO) channels over flat Rayleigh fading via the order statistics analysis. Simplified expressions are derived for expectations of the vector energies when the column (or row) number is equal to 1 and 2, which is followed by the upper and lower bounds when the antenna number at one side approaches infinite. Finally, some applications of the analysis, such as the computation of antenna selection and diversity gain, are discussed.更多还原
