UV NLOS Communications Atmospheric Channel Model and Its Performance Analysis

The free-space ultraviolet non-line-of-sight communication system has become a hot research topic in the field of wireless communication system for its safety and efficiency. To study the feature of UVNLOS communication system, according to the classic Mie scattering theory, the single-scattering atmospheric channel model and the multi-scattering atmospheric channel model have been built in this paper. And the different performances of these two models also are analyzed. The simulation results show that if the photonpsilas path length is short, the single scattering model is suitable; if the path length is long, because the multiple-scattering effect is in the primary place, there is a certain error between the single scattering model and experimental results, and the multi-scattering model should be used. A reference for the further development of UV non-line-of-sight communications systthe further development of UV non-line-of-sight communications systemem is provided in this paper.
