AI 中文摘要
本文研究相关复合广义Gamma(GG)/GG衰落信道上的物理层安全(PLS),其中阴影衰落与小尺度衰落均服从GG分布。利用Mellin变换和Fox-H函数,推导了单链路概率密度函数(PDF)、联合分布、生存函数及零速率保密中断概率(SOP)/非零保密容量概率(PNZSC)的闭式表达式。一般速率SOP表示为精确二重级数,每一项含一个残差一维积分;该模型将Nakagami-m/GG和Nakagami-m/Gamma信道作为特例包含在内。数值结果验证了分析的正确性,并表明衰落参数对保密性能的影响。
英文摘要
This paper investigates physical-layer security (PLS) over correlated composite generalized-Gamma (GG)/GG fading channels, where both shadowing and small-scale fading follow GG distributions. Using Mellin transforms and Fox-H functions, closed-form expressions are derived for the single-link probability density function (PDF), joint distribution, survival function, and zero-rate secrecy outage probability (SOP)/probability of non-zero secrecy capacity (PNZSC). The general-rate SOP is expressed as an exact double series with one residual onedimensional integral per term. The model includes the Nakagamim/GG and Nakagami-m/Gamma channels as special cases. Numerical results validate the analysis and demonstrate the impact of the fading parameters on secrecy performance.
