Channel characterization of full-duplex VLC system for urban tunnels

Abstract

Shortly, many communication dependent processes will be deployed in cities. However, there are scenarios where traditionally RF solutions cannot provide communication. Visible Light Communication has recently emerged as a favorable complement to RF to cover this need. In particular, the vehicular tunnel are a major challenge, where the communication needs to be redundant. This paper presents a full-duplex VLC system for vehicular tunnels. The system allows communication between vehicle and infrastructure using the vehicle's lamps and tunnel lighting system. Simulations are conducted to analyze the performance of the communication system links. Them demonstrate that VLC full-filled the minimum requirements.
