The identification of wavelet modulation based on trigonometric moments
Jinqiang Tian, Xianghong Tang, Yueli Li · 2007
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.
