Performance Analysis of Ultraviolet Communication System in Fog Environment

Based on the analysis of ultraviolet single scattering channel model, the attenuation model of fog and its impact on signal attenuation is investigated. Under foggy environment, the study on the performance of ultraviolet communications is carried, simulation results show that the fog will not only make ultraviolet communication system BER performance deterioration, but also make information transmission rate substantially lowered. In addition, to guarantee a certain system performance indicators, the average transmitted optical power will have higher requirements.
