A New Receiving System of Visible Light Communication for ITS
This paper discusses a new receiving system for visible light communication applied to intelligent transport systems (ITS). We use a light emitting diode (LED) traffic signal as a transmitter that sends information to vehicles that feature a receiver. There are, however, several problems associated with applying visible light communication to the field of ITS. First, we have to transmit information over long distances; second, the relationship between the transmitter and the receiver position changes with time; and third, the communication is affected by a lot of optical noise. Here, we propose a new receiving system to solve these problems and construct a prototype. Evaluation experiments on the system demonstrate its validity.
