A Dual-Receiving Visible-Light Communication System for Intelligent Transportation System

Wireless communication has been identified as the key enabling technology in Intelligent Transportation System (ITS). Visible-light communication (VLC) presents an alternative to other existing wireless technologies to enable infrastructure-to- vehicle communication in ITS. In this paper, we identify the major limitations in implementing VLC on outdoor environment. Next, we introduce a new and innovative receiver design with dual reception and effective ambient-light rejection capabilities. Simulation results show that our newly proposed receiver is able to achieve greater communication range and receivable information with an average improvement of 20 m and 10 Mbits during daytime, respectively.
