论文摘要
水下无线光学通信（UWOC）的单个孔径接收不足以应对温度梯度和气泡的综合作用引起的海洋湍流。本文分析了以混合指数概括性γ（EGG）分布为特征的通道辐照度波动下的UWOC多孔径的性能。我们通过使用选择组合（SC）和最大比率组合（MRC）接收器来分析系统性能。特别是，我们得出基于SC的多孔UWOC接收器的确切中断概率表达式，并在基于MRC的多孔UWOC接收器的中断概率上获得上限。借助派生结果，我们通过分析获得了所考虑的多孔UWOC系统的多样性顺序。
Single aperture reception for underwater wireless optical communication (UWOC) is insufficient to deal with oceanic turbulence caused by the combined effect of temperature gradient and air bubbles. This paper analyzes the performance of multi-aperture reception for UWOC under channel irradiance fluctuations characterized by the mixture exponential generalized gamma (EGG) distribution. We analyze the system performance by employing both selection combining (SC) and maximum ratio combining (MRC) receivers. In particular, we derive the exact outage probability expression for the SC-based multi-aperture UWOC receiver and obtain an upper bound on the outage probability for the MRC-based multi-aperture UWOC receiver. With the help of the derived results, we analytically obtain the diversity order of the considered multi-aperture UWOC system.
