摘要
In this paper the indoor visible light communication(VLC) multipath channel model is analyzed.A new reflection model based on the Lambert-Phong pattern is presented by investigation of the reflection characteristics.Through the MonteCarlo ray tracing simulation based on the Lambert-Phong pattern,the VLC optical channel models are set up,including the single source and multiple-source systems.The simulation results show that using the Lambert-Phong reflection pattern,the calculation becomes linear to the number of reflections and the computation complexity is decreased.
