摘要
为了降低红绿蓝发光二极管(RGB-LED)可见光通信系统解复用过程中滤光造成的光能量损失,设计了一种基于分光解复用法的RGB-LED可见光通信系统。介绍了分光解复用法的原理和结构组成,对比了分光解复用法与常用的滤光解复用法在解复用过程中的光能量损失,由对比结果可知,分光解复用法可降低滤光造成的光能量损失,提高光源的利用率。利用光通信仿真软件对通信系统进行了仿真测试,仿真结果显示,在相同误码率条件下,采用分光解复用法的系统能有效延长信号的传输距离。
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.
