一种基于微波二维码的车牌信息识别通信系统
A Communication System Based on Microwave QR Code for License Plate Information Recognition
摘要
Abstract
In this paper,intelligent reflecting surface(IRS)is used as an information medium to carry microwave QR codes containing license plate information.Specifically,RS can form a dynamic bitmap image by adjusting the amplitude and phase of its array of elements.Therefore,IRS can be used to display microwave QR codes,and the transceiver can obtain QR code information by radiating electromagnetic waves and receiving reflected signals from the IRS.Based on this idea,a QR code communication system model based on the IRS is first established,and some basic communication system operation mechanisms are investigated,including the derivation of the average bit error probability for signal modulation,the realization of QR codes on the IRS,transmission design,and detection.Simulations show the achievable communication performance of the system and confirm the feasibility of IRS-based microwave QR codes.关键词
