本文研究了单输入单输出（SISO）系统在衰落信道下的保密性能，即主信道和窃听者信道分别受到Rician/Nakagami-m$衰落和Nakagami-m$/Rician衰落的影响，并推导出了非零保密容量存在概率和保密容量中断概率的解析表达式。虽然许多作者已经分析了SISO系统在各种衰落下的保密性能，但在我们假设的情况下的保密性能还没有得到澄清。此外，模拟和数值结果表明，使用Rician和Nakagami-$m$衰落之间的近似的结果是不够的，在评估这些概率，因为只有近似的概率密度函数的主体，我们的分析是有效的。
In this paper, we investigate the secrecy performance of single-input single-output (SISO) system over fading, such that the main channel and the eavesdropper channel are subject to Rician/Nakagami-$m$ fading or Nakagami-$m$/Rician fading, and derive the analytical expressions of the probability of the existence of the non-zero secrecy capacity and the outage probability of secrecy capacity. Although many authors have analyzed the secrecy performance of SISO system over various fading, the secrecy performance in the cases we assume has not been clarified. Furthermore, the simulation and numerical results show that the results using the approximation between Rician and Nakagami-$m$ fading is insufficient in evaluating those probabilities because of only approximation to main bodies of the probability density function, and that our analyses are valid.
