摘　　要：RFID(radio frequency identification)测试技术已成为RFID技术研发和应用实施过程中的重要技术保障。提出了一种新的基于LabVIEW的RFID调制方式测试方法。在软件无线电的基础上,采用四个特征参数,通过由图形化编程语言LabVIEW实现对2ASK、4ASK、2FSK、4FSK和BPSK等RFID系统典型调制方式进行识别。讨论了方案设计,给出了仿真实验结果。仿真结果表明,该方法具有较好的识别率和实时特性。Testing technology for RFID has become the significant guarantee for further development of RFID technique. This paper proposed a new testing methodology based on software radio for RFID signal modulation which, by means of 4 characteristic parameters and LabVIEW environment, could make identification among 5 modulation types, including 2ASK, 4ASK, 2FSK, 4FSK and BPSK effectively. Discussed the design procedure and presented simulation results. The results of simulation show that this method can obtain a significant recognition effect and a fine real-time performance even with a low SNR.
