论文摘要
通过与离散输入的混合伽马（MG）分布式褪色通道研究了物理层安全性。根据高斯正交规则，得出封闭式表达式以表征平均保密率（ASR）和保密中断概率（SOP），其准确性通过数值模拟验证。为了显示有限词组信号传导的更多属性，我们对主通道的平均信噪比（SNR）的大限制进行了对保密指标的渐近分析。利用Mellin转化，我们发现，随着平均SNR的增加，ASR和SOP会收敛到某些常数，并得出新颖的表达以表征收敛速率。这项工作为通过离散输入实现的保密性能建立了一个统一的一般分析框架。
Physical layer security is investigated over mixture Gamma (MG) distributed fading channels with discrete inputs. By the Gaussian quadrature rules, closed-form expressions are derived to characterize the average secrecy rate (ASR) and secrecy outage probability (SOP), whose accuracy is validated by numerical simulations. To show more properties of the finite-alphabet signaling, we perform an asymptotic analysis on the secrecy metrics in the large limit of the average signal-to-noise ratio (SNR) of the main channel. Leveraging the Mellin transform, we find that the ASR and SOP converge to some constants as the average SNR increases and we derive novel expressions to characterize the rates of convergence. This work establishes a unified and general analytical framework for the secrecy performance achieved by discrete inputs.
