摘　　要：针对海上可见光通信波长选择的问题,分析了影响海上可见光通信的背景光模型和大气湍流信道模型,分别得出了两者对可见光通信质量产生影响的关键因子。根据背景光模型公式与Gamma-Gamma大气湍流模型公式,计算推导出在强光背景和大气湍流同时影响下的可见光通信误码率。对3种条件下可见光通信系统进行了仿真,得出了在不同通信距离、折射率结构参数、视场角条件下,光源波长与误码率的相关关系。该关系的明确,为海上可见光通信光源波长选择提供了理论依据。In order to address the issue of wavelength selection in offshore visible light communication,this study analyzed the background light model and atmospheric turbulence channel model that impacted marine visible light communication.The key factors that influenced the quality of visible light communication were identified.Simulations of the visible light communication system under three different conditions were also conducted.These simulations provided insights into the correlation between the light source wavelength and the bit error rate.Specifically,the correlation was examined under varying communication distances,refractive index structure parameters,and field angles.The obtained results serve as a foundation for selecting the appropriate light source wavelength in offshore visible light communication.
