A simplified NLOS UV communication model

Ultraviolet (UV) is a promising enabling technology for non-line-of-sight (NLOS) optical wireless communication. The UV signal transmission undergoes rich scattering and strong absorption by atmospheric particulates. This paper briefly introduces the characteristic of UV atmospheric transmission and the propagation model based on prolate spheroidal coordinate system. According to two different kinds of UV communication model, this paper presents simplified computing methods of Non-Line of Sight single scattering channel model; The simulation results show that the simplified models not only achieve accelerated ratio of 105, but also assure the simulation accuracy; Base on this model, it is easy to simulate and analysis the energy loss with different transmitting distance and variety weather conditions, which provides a theoretical basis for fast energy analyzing of UV communication system.
