Simulation research of short range non-line-of-sight ultraviolet communication performance

The non-line-of-sight single scattering channel model is significantly simplified by means of a closed-form expression. Based on such an approximation, the relationship between visibility and path loss of the ultraviolet communication system is analyzed, and the result is accordance with that obtained from original model. Moreover, the simulations of bit-error-rate indicate that path loss of communication channel has a lowest value and data rates have a highest value under fixed BER requirements when visibility is a critical point. The data rates which meet the different BER requirements are in the same order of magnitude at a given visibility and distance.
