The Link Attenuation Model Based on Monte Carlo Simulation for Laser Transmission in Fog Channel

摘要: Free space optical (FSO) systems were usually designed according to the link budget analysis. However, previous attenuation estimations for fog channel not precise. The would be distorted, and resulting in robustness degeneration of FSO system. Therefore, it is necessary establish an accurate model channel. models mainly adopted by Beer-Lambert law, or classical Monte Carlo simulation combined with drop size distribution. Unfortunately, estimation deviation was eventually fall within acceptable range We established a based on Kim formula. Our took influence multiple scattering receiving parameters into consideration, without measurement distribution cross-sections. experiment set up verify analysis results. And results revealed that RMSE (root mean square error) $ , which validated accuracy model. can used strengthen system guide parameter design future communication under
