Fundamental Analysis of Vehicular Light Communications and the Mitigation of Sunlight Noise

Intelligent transport systems (ITS) rely upon the connectivity, cooperation and automation of vehicles aimed at improvement safety efficiency system. Connectivity, which is a key component for practical implementation vehicular light communications (VeLC) in ITS, must be carefully studied prior to design implementation. In this paper, we carry out performance evaluation study on use different vehicle taillights (TLs) as transmitters VeLC We show that, transmission coverage field view link span depend TLs illumination patterns transmit power levels, respectively, fail meet typical communication distances environments. This paper proposes an infrared-based system range daytimes under Sunlight noise. forward error correction bit rate limit 3.8 ×10 -3 , proposed are 63, 72, > 89 m compared with 4.5, 5.4 6.3 BMW's TL data rates 10, 6, 2 Mbps, respectively.
