论文摘要
在本文中，我们调查了替代的里克利亚阴影褪色通道上的物理层安全性，这是一个新颖的频道模型，用于身体以身体为中心的无线链接和陆地移动卫星。我们得出了平均保密能力（ASC），秘密中断概率（SOP）的精确闭合表达式，并且在两种情况下非零保密能力（PNZ）的概率：（i）M是一个正数，（ii）M是一个正数，M是正整数，其中M是一个正整数，其中M描述了“线”的波动水平。在第一种情况下，SOP是根据Meijer的G功能得出的，而ASC和PNZ则是根据多元FOX的H功能得出的。在第二种情况下，ASC是根据Meijer的G功能得出的，而SOP和PNZ则是根据基本功能得出的。此外，我们得出了渐近ASC，SOP和PNZ表达式，它们分别在高信噪比值的高值时匹配确切的表达式。渐近ASC的容量斜率和渐近SOP的保密多样性顺序已得出，以提供更多的物理见解。最后，通过蒙特卡洛模拟验证了我们派生表达式的准确性。
In this paper, we investigate the physical layer security over the Alternate Rician Shadowed fading channel, which is a novel channel model for body-centric wireless links and land mobile satellite. We derive exact closed-form expressions for the average secrecy capacity (ASC), secrecy outage probability (SOP), and probability of non-zero secrecy capacity (PNZ) for two cases: (i) m is a positive real number and (ii) m is a positive integer number, where m describes the level of fluctuation of the line-of-sight component. In the first case, SOP is derived in terms of the Meijer's G-function, while ASC and PNZ are derived in terms of the multivariate Fox's H-function. In the second case, ASC is derived in terms of the Meijer's G-function, while SOP and PNZ are derived in terms of elementary functions. In addition, we derive the asymptotic ASC, SOP and PNZ expressions which all match well the exact ones at high values of signal-to-noise ratio, respectively. The capacity slope of asymptotic ASC and the secrecy diversity order of asymptotic SOP have been derived for providing more physical insights. Finally, the accuracy of our derived expressions is validated by Monte-Carlo simulations.
