| Abstract: | The testing methods of RFID take great theoretical and practical significance for the RFID systems, and test/recognition of RFID modulation signals has become one of the most important parts of the RFID testing methods. A new test methodology for RFID signal modulation based on software radio is proposed which, by use of 4 characteristic parameters and a BP classifier based on artificial neural networks, could make correct identification among 5 modulation types, including 2ASK、4ASK、2FSK、4FSK and BPSK. The design procedure is discussed and simulation results are presented. The result of the experiments proves that this method has a significant recognition accurately and real time even with a low SNR. |
