- These days, research related to Intelligent Transportation System (ITS) technology is being widely considered.
ITS is inevitable for future transportation systems to reduce accidents, congestion, and offer a smooth flow oftraffic. The use of Visible Light Communication (VLC) in ITS systems has been considered widely because ofits EMC/EMI free and LED infrastructure reusable properties. Among the VLC schemes, this study analyzed theperformance of the Color Shift Keying (CSK) scheme under a Vehicle-to-Infrastructure (V2I) downlink scenarioto verify the capability of CSK as a communication tool for ITS. By modeling daylight noise using the modifiedBlackbody radiation model, this study examined the performance of V2I VLC under daytime conditions. Therelationship between BER, the communication distance, and the amount of ambient-light noises under thepre-described V2I scenario were determined by simulations.
