Modeling of Pedestrian Occlusion Vehicular Visible Light Communication System

In this study, we propose a model of the vehicular two-input two-output visible light communication system under pedestrian occlusion. We analyse the number of pedestrians and the position situation. Calculate the probability of pedestrian occlusion to obtain the performance parameters of the communication system, and verify that the effect of pedestrian occlusion on the vehicular visible light communication system is not negligible. Moving vehicles in adjacent lanes create interference but are also potential reflectors. Analyse the effects of different positions of moving vehicles and crossing pedestrians on the V-VLC system. The results show that when the distance between the moving vehicle and the transmitting vehicle is in the vicinity of 0.8 times the longitudinal distance of the communicating vehicle, the bit error rate value decreases to about 50% of that of the communication system without moving vehicles. Moving vehicles affect the performance of the communication system and this effect is positive.
