On-channel characteristics of wireless ultraviolet communication with mobile terminals

Abstract

Most studies of ultraviolet communication do not consider the mobility of communication terminals. In this Letter, a single-scattering-channel model based on the Monte Carlo method is proposed for non-line-of-sight ultraviolet communication with mobile terminals. Our main contribution is to present an original method of evaluating the impulse response of communication channels given the relative moving speed and direction of the terminals. Using this method, the impact of the moving speed and direction of the terminals on the system response is simulated. Our simulation results show that the transmission distance plays a dominant factor in all scenarios, whether the communication terminals are coplanar or noncoplanar and with or without a height difference.
