In this Letter, we use laser beam intensity fluctuation measurements to model and describe the statistical properties of weak temperature-induced turbulence in underwater wireless optical communication (UWOC) channels. UWOC channels with temperature gradients are modeled by the generalized gamma distribution (GGD) with an excellent goodness of fit to the measured data under all channel conditions. Meanwhile, thermally uniform channels are perfectly described by the simple gamma distribution which is a special case of GGD. To the best of our knowledge, this is the first model that comprehensively describes both thermally uniform and gradient-based UWOC channels.
在本信函中，我们利用激光束强度波动测量来建模和描述水下无线光通信（UWOC）信道中由温度引起的微弱湍流的统计特性。具有温度梯度的UWOC信道由广义伽马分布（GGD）建模，在所有信道条件下，该分布与测量数据具有极佳的拟合优度。同时，热均匀信道由简单伽马分布完美描述，简单伽马分布是GGD的一种特殊情况。据我们所知，这是第一个全面描述热均匀和基于梯度的UWOC信道的模型。
