研究成果概要

  In this research project, a hybrid visible light and radio communication for location-specific services in intelligent transportation system is studied. This location-specific communication using visible light allows the receiver at the vehicle to display to the driver only that traffic information which is relevant to the location, which the vehicle is. Moreover, the drivers will not be bothered with traffic information irrelevant to them (e.g. those only relevant to neighboring lanes) and the user experience is improved. Nevertheless, it is well known that VLC cannot compete with radio frequency (RF) systems when it comes to long-distance transmission. A hybrid system that makes use of VLC and RF communication is proposed to solve the above problem. In the proposed hybrid system, the transmitted information is divided between the VLC channel and the RF channel. VLC channel is used to maintain the positioning capability and RF channel is used to send most of the information. The theoretical work and simulation have been done to show the effective communication area and the receivable information can be increased by using the proposed system compared with a pure VLC system.
