Abstract
Recently, the IT convergence technology using LED such as Visible Light Communication (VLC) is being emerged. Among many VLC applications, vehicular vehicle-to-vehicle (V2V) VLC based on LED headlamp is possible to use in Intelligent Transportation Systems (ITS) or Active Safety application. In this paper, we introduce the demonstration of vehicular VLC system based on LED headlamp. Based on inverse 4-PPM scheme with 75% dimming and prototype LED headlamp, our system shows a potential for V2V VLC with 10kbps data rate in about 20m distance at day time scenario.
