Abstract

This paper presents a mathematical model for car-to-car (C2C) visible light communications (VLC) that aims to predict the system performance under different communication geometries. A market-weighted headlamp beam pattern model is employed. We consider both the line-of-sight (LOS) and non-line-of-sight (NLOS) links, and outline the relationship between the communication distance, the system bit error rate (BER) performance and the BER distribution on a vertical plane. Results show that by placing a photodetector (PD) at a height of 0.2-0.4 m above road surface in the car, the communications coverage range can be extended up to 20 m at a data rate of 2Mbps.
