Understanding the effect of ocean turbulence on optical beam propagation is critical to the design and performance evaluation of underwater wireless optical communication systems. In this Letter, we propose a unified Weibull-generalized gamma distribution to characterize the laser beam irradiance fluctuations of turbulent underwater thermocline wireless optical channels. The proposed model shows an excellent agreement with the measured data under various experimental emulated channel conditions that cover turbulences induced by temperature, salinity, and air bubbles. To the best of our knowledge, this is the first model that comprehensively describes the statistics of the laser beam irradiance fluctuations in underwater wireless optical channels due to both thermohaline gradient and air bubbles.
理解海洋湍流对光束传播的影响对于水下无线光通信系统的设计和性能评估至关重要。在这封信中，我们提出了一个统一的威布尔广义伽马分布来描述海洋跃层无线光信道中激光束辐照度波动。该模型在各种实验模拟信道条件下与测量数据具有很好的一致性，这些条件涵盖了由温度、盐度和气泡引起的湍流。据我们所知，这是第一个全面描述由于热盐梯度和气泡引起的水下无线光信道中激光束辐照度波动的统计模型。
