摘要
介绍了基于UHF Class 1 Generation2协议标准的RFID系统的调制、解调算法。在FPGA上实现了调制器和解调器,调制器可根据用户需要选择DSB-ASK、SSB-ASK或PR-ASK调制方式,解调器能同时解调2ASK和BPSK信号。使用QuartusⅡ与MATLAB联合仿真,结果表明设计的RFID调制器和解调器是正确的。
The modulation and demodulation method of RFID system based on UHF Class 1 Generation 2 protocol are discussed. The modulator and demodulator are implemented on FPGA, where the modulator can use DSB-ASK, SSB-ASK or PR-ASK according to user needs, and the demodulator support both 2ASK and BPSK signal. Quartus II and MATLAB are used for simulation, and results validate the imple- mented RFID modulator and demodulator.
