基于分光法的RGB-LED可见光通信系统
A Kind of RGB-LED Visible Light Communication System based on Dichroic-Demultiplexing Method
摘要
Abstract
In order to reduce the light energy loss caused by the demultiplexing process of Red Green Blue Light Emitting Diode (RGB-LED)visible light communication system,an RGB-LED visible light communication system based on dichroic-demulti-plexing method is designed.The principle and structure of dichroic-demultiplexing method are first introduced.Then the light energy loss in demultiplexing process is compared between dichroic-demultiplexing and the commonly used filter-demultiplex-ing.From the comparison results,dichroic-demultiplexing method can reduce the light energy loss caused by filtering,and im-prove the utilization of light sources.Then the communication system is simulated,and the simulation results show that under the same bit error rate,the system with dichroic-demultiplexing can effectively increase the transmission distance.关键词
