Analysis of the Transmission Characteristics of Ultraviolet Communication in Non-Common-Scattering Volume

Abstract

This paper uses multiple scattering model based on Monte Carlo simulation to study the transmission characteristics of uv communication in non common scattering volume And theoretically analyze the performance of the omnidirectional full-duplex UV optical communication system. In the model, the variation of the average scattering times of uv light in the atmosphere, the variation of the path loss, the change of the pulse response time delay and signal to noise ratio (SNR) along with the transmission distance. And the variation of signal to noise ratio of full duplex communication system based on WDM technology are analyzed in the omnidirectional directional scattering case. The results show that unlike the case of a common scattering volume at least twice atmospheric scattering are required to reach. the receiving end in non-common-scattering volume model, The path loss and impulse response time delay with the same transmission distance for the non public scattering transmission model is much higher than those the common scattering volume transmission model. The interference signal-to-noise ratio of full-duplex communication system based on theory of wavelength division multiplexing is much smaller than that of the common scatter transmission model. The full duplex UV communication can be realized by WDM technology. The results show that the theory of WDM technology can realize omnidirectional full-duplex UV communication. When the transmission power is increased and the detection efficiency is improved, the application requirements can be fully satisfied. The paper theoretically gives the ultraviolet transmission characteristics of the transmission model without common scatterers, and provides theoretical basis and favorable reference value for the study of omnidirectional communication of actual ultraviolet light.
