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-demultiplexing 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-demultiplexing.From the comparison results

dichroic-demultiplexing method can reduce the light energy loss caused by filtering

and improve 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.
