采用ACO-OFDM调制新型可见光-射频识别标签系统
New kind of visible light-RFID with ACO-OFDM modulation
摘要
Abstract
A new kind of visible light RFID system with Asymmetrically Clipped Optical Orthogonal Frequency Division Multiplexing (ACO-OFDM) modulation is proposed for concern over the radiative and unstable of the traditional radio frequency identification. The system combines ACO-OFDM modulation technology with visible light communication (VLC) technology to read tags. In order to improve the stability of the signal, ACO-OFDM modulation is implemented in the system to resist the intersignal interference and improve the bandwidth utilization. In the paper, we introduce the terminal tag chip, modem, optical emitter and receiver in turn. The terminal tag chip, emitter and receiver circuit have been implemented in0.18μm CMOS process. The modulation and demodulation module is based on FPGA. According to the simulation, digital and analog part of the system can work properly and realize the operation to the tags.关键词
