A SNR analysis of the visible light channel environment for visible light communication

Abstract

In this paper, we provide Signal-to-Noise Ratio (SNR) analysis of visible light channel environment reflecting practical conditions for the usage of Visible Light Communication (VLC) in Intelligent Transportation System (ITS). Considering practical LED lights (Headlamp and Streetlamp), we perform 3D computer simulations in two ITS scenario. Through simulation, we can notice that VLC can be used even in day time in Vehicle-to-Infra (V2I) scenario cases. However, more study about how to mitigate day time ambient noise is still required to support VLC in day time Vehicle-to-Vehicle (V2V) scenario.
