摘要:
为了解决现有通信方式频谱资源紧张、电磁污染等问题,频谱宽、绿色节能、移动性强的可见光通信(VLC)技术应运而生。设计一套LED可见光点对点数据收发系统,由于数据传输对硬件要求比较高,此设计使用了现场可编程门阵列(FPGA)作为硬件平台,提高运算速率;在光检测器(PD)前使用光集中器以使足够的光被光检测器接收,同时在接收端前端获得理想的照度;在接收端前端使用蓝光滤光片滤除响应慢的黄光分量及其他波段的干扰光。经测试,系统在保证文件正确传输的前提下,可以实现高达2.43 Mbps的数据传输速率。由系统验证可知,传输速率的提升会使系统误码性能下降,而照度的提高会使系统误码性能提高。
Abstract:
In order to solve the problem of spectrum resource scarcity, electromagnetic pollution and other problems in the existing communication methods, the spectrumwide, green energysaving and mobilestrong visible light communication (VLC) technology came into being. This paper designed an indoor LED visible light data receiving and transmitting system. As the data transmission in the hardware requirements were relatively high, this design used a FieldProgrammable Gate Array (FPGA) as the hardware platform to improve the operation rate; We used a light concentrator in front of the photodetector (PD) so that sufficient light could be received by the photodetector and the desired illuminance could be obtained at the front end of the receiver. In front of the receiver, a blue filter was used to filter out the yellow component which responsed slowly and the interference light on other bands. By testing, we found that the system achieved up to 2.43Mbps data transmission rate under the guarantee that the files transferred correctly. Finally, through the verification of the system, it was concluded that the increase of the transmission rate would degrade the system BER performance, and the increase of the illuminace would improve the system BER performance.
