Abstract
The recent interest in short-range optical wireless communication technology driven by the widespread deployment of solid state lighting has led to significant efforts on the standardization of visible light communication. In such efforts, the consideration of dimming support poses fundamental challenges on the VLC system design that have not been addressed elsewhere. This article overviews the technical considerations for enhancing the VLC physical layer by summarizing the state-of-the-art advancements in modulation and coding technologies dedicated to VLC systems. In addition, the technical challenges for system enhancement under lighting restrictions are described.
