Abstract
Non-line-of-sight (NLOS) ultraviolet (UV) scattering channel impulse response in the deep UV solar-blind spectrum band is investigated. Taking into account a light source power angular distribution and applying a photon tracing technique, Monte Carlo simulation is performed to obtain the channel impulse response and associated path loss. Some comparisons are carried out with an existing single scattering channel model, as well as field measurements in both the impulse response model and path loss, to demonstrate modeling accuracy. The importance of considering multiple versus single-scattering in the analysis is shown. The results provide guidelines for study of limitations to data rate and communication range in NLOS UV communications.
