The correlation function of localized Lommel-Gaussian vortex beams is obtained in oceanic turbulence and used to estimate the channel capacity of underwater wireless optical communication systems (UWOCS). The effects of laser source and oceanic turbulence on the channel capacity are discussed. Results show that the choices of appropriate light parameters, such as input pulse half-width, beam waist, and orbital angular momentum number, are essential to achieve high channel capacity in UWOCS. Another important factor that affects channel capacity is oceanic turbulence. Scaling analysis shows that inner scale has a more significant effect on the channel capacity than the outer scale does.
在海洋湍流中获得了局域化洛梅尔 - 高斯涡旋光束的相关函数,并用于估计水下无线光通信系统(UWOCS)的信道容量。讨论了激光源和海洋湍流对信道容量的影响。结果表明,选择合适的光参数,如输入脉冲半高宽、束腰和轨道角动量数,对于在UWOCS中实现高信道容量至关重要。影响信道容量的另一个重要因素是海洋湍流。标度分析表明,内尺度对信道容量的影响比外尺度更为显著。
