论文摘要
我们使用解码和前向（DF）继电器分析了两跳混合射频（RF）/水下无线光学通信（UWOC）系统的保密性能。所有RF和UWOC链接均分别由$α-μ$和指数性伽马分布进行建模。我们首先以精确的闭合形式得出保密中断概率（SOP）的表达，随后将其用于在高SNR处得出渐近表达式，该表达仅包含简单的函数以进一步洞察力。此外，根据渐近表达，我们可以确定各种RF和UWOC通道条件的最佳发射功率。使用蒙特卡洛模拟对所有分析进行验证。
We analyze the secrecy performance of a two-hop mixed radio frequency (RF)/underwater wireless optical communication (UWOC) system using a decode-and-forward (DF) relay. All RF and UWOC links are modeled by the $α-μ$ and exponential-generalized Gamma distributions, respectively. We first derive the expressions of the secrecy outage probability (SOP) in exact closed-form, which are subsequently used to derive asymptotic expressions at high SNR that only includes simple functions for further insight. Moreover, based on the asymptotic expression, we can determine the optimal transmit power for a wide variety of RF and UWOC channel conditions. All analyses are validated using Monte Carlo simulation.
