The characteristic parameter extraction and automatic identification technology of wireless digital signal modulated by single carrier and multicarrier based on decision theory algorithm are researched mainly and then the decision classifier
the identification steps corresponding which suitable for single carrier and multicarrier digital modulation recognition are put forward.A phase folding algorithm to correct the influence of phase folding was first used in instantaneous phase extraction and the accuracy of characteristic parameters was improved. The simulation results show it has good recognition effect
the system is easy to realize and it has a broad prospect of application in the signal recognition.
