Addressing the Challenges in V2X Visible Light Communications

Visible Light Communications (VLC) is gaining momentum for vehicular communication with the availability of abundant bandwidth and inherent short-range confinement. However, outdoor vehicular VLC systems are exposed to multitude of challenges such as, rapidly varying channel conditions, highly directional property of light rays and the high ambient noise interference, especially from the Sun. Unipolar nature of intensity modulated VLC systems precludes directly adopting many wireless signal processing solutions. We have been investigating number of solutions in Ryerson Communications Lab to overcome these challenges.
