In this paper, exact closed-form expressions are derived for the outage probability (OP) of the maximal ratio combining (MRC) scheme in the κ-μ shadowed fading channels, in which both the independent and correlated shadowing components are considered. The scenario assumes the received desired signals are corrupted by the independent Rayleigh-faded co-channel interference (CCI) and background white Gaussian noise. To this end, first, the probability density function (PDF) of the κ-μ shadowed fading distribution is obtained in the form of a power series. Then the incomplete generalized moment-generating function (IG-MGF) of the received signal-to-interference-plus-noise ratio (SINR) is derived in the closed form. By using the IG-MGF results, closed-form expressions for the OP of MRC scheme are obtained over the κ-μ shadowed fading channels. Simulation results are included to validate the correctness of the analytical derivations. These new statistical results can be applied to the modeling and analysis of several wireless communication systems, such as body centric communications.
本文推导了κ-μ阴影衰落信道中最大比合并（MRC）方案中断概率（OP）的精确闭式表达式，其中同时考虑了独立和相关的阴影分量。该场景假设接收到的期望信号受到独立瑞利衰落同信道干扰（CCI）和背景白高斯噪声的影响。为此，首先以幂级数形式获得κ-μ阴影衰落分布的概率密度函数（PDF）。然后以闭式形式推导接收信号与干扰加噪声比（SINR）的不完全广义矩生成函数（IG-MGF）。通过使用IG-MGF结果，在κ-μ阴影衰落信道上获得了MRC方案OP的闭式表达式。给出了仿真结果以验证解析推导的正确性。这些新的统计结果可应用于多种无线通信系统的建模和分析，如人体中心通信。
