Abstract

The photon counting detection model and the multi-scattering photon propagation model were used to investigate the effects of atmosphere visibility on the path loss and delay spread of an ultraviolet scattering channel with a vertical transmitter-receiver and the achievable data rate with on-off keying (OOK) modulation. Simulations show that, at a given communication range, the delay spread increases with improving atmosphere visibility. When the communication range is set, there is a best visibility where the minimum path loss occurs and this best visibility increases with increasing communication range. For a given communication range, there are a best visibility and an optimum baud rate that maximize the achievable data rate. With large communication ranges, the best visibility increases while the optimum baud rate and the corresponding maximum achievable data rate decrease.
