Abstract :
Wavelet modulation (WM) is a new type of modulation. This paper mainly studies the identification of wavelet modulated signals. Since the signal´s instantaneous frequency evaluated with radian is circular, we extract a feature which is based on high order trigonometric moment of signals´ instantaneous frequency to identify wavelet modulation. The computer simulation result indicts that the feature is robust and good performance is obtained.
