| 摘 要： | 通过MATLAB对实时频谱仪采集的RFID读写器与标签通信的射频信号原始数据样本离线读入,实现了对读写器命令、标签响应数据的时域、频域和解码分析,验证读写器、标签射频信号是否满足协议的一致性。由于仅使用了仪器采集的原始I/Q信号,具体分析工作通过MATLAB编程完成,最大程度地减少了对仪器的依赖,同时能针对不同空中接口协议适当修改源码,提高了读写器标签射频信号数据分析的灵活性。这种方法对分析不同的RFID空中接口数据具有较强的通用性。

| Abstract: | Original I/Q signal data of air interface collected by real-time spectrum analyzer can be offline analyzed in frequency domain,time domain and code domain with MATLAB.We can parse the command of Interrogator and response of Tag and verify whether them accord with RFID protocols.Due to only using the original I/Q signals,we can analyse signal based on different RFID Protocols through MATLAB by changing source code,that minimize the dependence on to the instrument.This method offers greater flexibility in signal analysis based on different RFID protocols. |
