水下光学无线通信中的海水信道特征主要体现在:海水信道具有散射以及吸收光数据信号的特征,这些特征导致光在海水中传输时,会出现衰减现象。基于衰减现象,水下光学无线通信中的海水信道特征模型主要包括衰减参数函数、光吸收函数、光散射函数以及经过衰减后接收光数据总能量。基于水下光学无线通信海水信道特征模型仿真分析主要包括:在水下光学无线通信中海水信道特征函数仿真验证以及传播误码率分析。
Seawater channel features in underwater optical wireless communications are mainly reflected in the fact that seawater channels have the characteristics of scattering and absorbing light data signals that cause attenuation of light as it travels in seawater. Based on the attenuation phenomenon, the seawater channel characteristic model in underwater optical wireless communication mainly includes the attenuation parameter function, the light absorption function, the light scattering function and the total energy of the received light data after attenuation. The simulation analysis of underwater water channel characteristics based on underwater optical wireless communication mainly includes the verification of seawater channel characteristic function in underwater optical wireless communication and the analysis of the bit error rate.
