本文给出了由两个广义随机变量之比表示的特殊构造随机变量的累积分布函数的表达式。所得到的理论结果被用来评估在η-μ衰落的感兴趣信号(SOI)、η-μ或κ-μ衰落的同信道干扰(CCI)以及背景高斯白噪声的情况下的中断概率。我们的结果也适用于SOI通过κ-μ衰落信道，并且干扰信号是η-μ衰落的场景。如果表示SOI分量或μ分量的统计分布的η-μ模型的所有参数CCI<sup>i</sup><sup>i</sup>都是整数，则可以使用导出的结果。特别地，我们证明了在前一种情况下，CDF是用初等函数表示的。
In this paper, we present expressions for the cumulative distribution function (CDF) of a specially constructed random variable (RV) represented by the ratio of two generalized RVs. The obtained theoretical results are used to evaluate the outage probability in scenarios with η-μ-faded signals of interest (SoI), η-μ- or κ-μ-faded co-channel interference (CCI), and background white Gaussian noise. Our results are applicable also to scenarios where the SoI passes through the κ-μ fading channel, and the interfering signals are η-μ-faded. The derived results can be used if all parameters μ<sub>i</sub> of the η-μ models representing the statistical distributions of either the SoI components or CCI components are integers. We prove, in particular, that in the former case, the CDF is expressed in terms of elementary functions.
