| 摘 要： | 最大比合并在无线通信的几种分集合并技术中是最优的。针对相关支路，证明了最大比合并等价于独立支路的最大比合并的性能，同时也证明了相关支路的输出信噪比的概率密度函数等于各个不相关支路的信噪比概率密度的加权和。该结论对于分析相关信道最大比合并的性能是有用的。

| Abstract: | It is proved that performance of maximal ratio combining with correlated diversity branches is optimal. In this paper, authors point out the performance of an equivalent diversity system with independent and unbalanced inputs, and verify that probability density function(PDF) of maximal ratio combining with correlated Rayleigh branches is identical to weighting the PDF of maximal ratio combining with individual Rayleigh branch. This conclusion is useful in analyzing. the maximal ratio combination in correlated channels. |
