Modeling and analysis of the wireless channel formed by LED angle in visible light communication

Abstract

Visible light communication (VLC) is expected to be the next generation of indoor wireless communication. Commonly, a VLC system uses many LED chips, and its performance is affected a lot by the placement of LEDs. In this paper, we propose LED panel model that can place LEDs with some angle. Based on the simulation results, the effect of changing LED directions is analyzed and the optimal direction of LED is pointed out. © 2012 IEEE.
