FPGA기반 가시광 통신링크를 이용한 차량용 메시지 전송시스템 개발

Abstract

According to the recent development of the visible light communication (VLC), many researches have been performed on improving the communication performance of VLC systems. The visible light communication is being developed for intelligent transportation system covering vehicle to vehicle communication. The visible light communication is being developed for intelligent transportation system covering vehicle to vehicle communication. In this paper, we propose and develop a car-to-car simple message delivery system, which supports immediate message identification and delivery of messages in one way backwards. The system is developed using a general-purpose field programmable gate array (FPGA) board for storing message set to be delivered and sending one out of the set of messages. The developed message delivery link is successful over 8 meter and the distance is easily extendable using increasing LED emission power at the transmitter and adopting concentrating optical devices at the receiver. And the proposed architecture is demonstrated experimentally and its performance is verified through the experimental results of quality-factor(Q-factor) and eye pattern.
