In this letter, we present the $\alpha $ - $\eta $ - $\mathcal {F}$ and $\alpha $ - $\kappa $ - $\mathcal {F}$ composite fading distributions. The two distributions generalize the two well-known composite fading distributions, namely the $\eta $ - $\mu $ /inverse gamma and the $\kappa $ - $\mu $ /inverse gamma distributions. For both distributions, we derive new exact closed-form expressions for the probability density function (PDF) and cumulative distribution function (CDF) of the instantaneous signal-to-noise ratio (SNR). Additionally, the outage probabilities (OPs) of a wireless communication system operating over the new composite fading channels are obtained. Moreover, we derive asymptotic OPs, in the high SNR regime, to gain more insight into the influence of fading parameters. Some numerical results on the envelope PDFs and OPs are provided and compared with Monte-Carlo simulation results to validate the analyses.

α-η-F 和 α-κ-F 复合衰落分布

在这封信中,我们介绍了 $\alpha $ —— $\eta $ —— $\mathcal {F}$ $\alpha $ —— $\kappa $ —— $\mathcal {F}$ 复合衰落分布。这两个分布概括了两个著名的复合衰落分布,即 $\eta $ —— $\亩 $ /逆伽玛和 $\kappa $ —— $\亩 $ /逆伽马分布。对于这两种分布,我们为瞬时信噪比 (SNR) 的概率密度函数 (PDF) 和累积分布函数 (CDF) 推导出新的精确闭式表达式。此外,还获得了在新的复合衰落信道上运行的无线通信系统的中断概率 (OP)。此外,我们在高 SNR 状态下推导出渐近 OP,以更深入地了解衰落参数的影响。提供了一些关于包络 PDF 和 OP 的数值结果,并与蒙特卡罗模拟结果进行了比较以验证分析。
