Research on transmission characteristics of wireless ultraviolet communication in floating dust weather based on the particle scale spectrum.

Abstract

Floating dust weather has a great impact on wireless ultraviolet (UV) communication (UVC). In this paper, the distribution of floating dust particle spectrum is considered. And a wireless UV scattering communication model in floating dust weather is established. The transmission characteristics of UV channel are studied by the segmentation of floating dust particle spectrum. In order to reduce the complexity of particle spectrum segmentation algorithm and the simulation time, an equivalent particle size method is proposed based on the particle scale spectrum segmentation method. At the same time, the equivalent concentration of equivalent particles is given. The simulation results show that the path losses calculated by the two methods can be well fitted. Outdoor experiments of wireless UVC under different floating dust weather conditions are carried out. The simulation results are consistent with the experimental results, which verify the effectiveness of the equivalent particle size method based on particle spectrum distribution.
