基于FPGA的室内可见光通信系统设计与实现
Design and Implementation of FPGA-based Indoor Visible Light Communication System
摘要
Abstract
Visible Light Communication(VLC)has the advantages of high communication rate,green environ-mental protection,high security,no need for spectrum licensing,etc,and has become a hot spot of research.In view of the complexity of the visible light communication system design and the problem of short communication distance,this paper adds a secondary amplifier circuit at the receiving end to further improve the anti-interference ability of the system,and at the same time,it also researches the channel model of the indoor visible light communication system and combines with the bright light-emitting diode to carry out the simulation and analysis of the light intensity,the received power,the signal-to-noise ratio and the bit error rate in the indoor space,and analyses the noise-resistant performance and the bandwidth utilization rate of the different modulation modes.Field Programmable Gate Array(FPGA)is used as the control chip of the optical communication system,the indoor visible light communication system based on 2PPM(Pulse-Phase Modulation,PPM)is designed.Communication performance of the system under the scheme is verified by building an experimental platform,Bit Error Ratio less than 1×10-5 at a communication distance of 3.5m,and the experimental results show that the communication system has the advantages of low Bit Error Ratio and simple structure,which meets the requirements of high-performance indoor visible light communication system.关键词
