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.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.
