%X 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.
