Wavelet modulation (WM) signal is a special kind of multi-carrier modulation signals (MCMS). Based on the time-frequency characteristics of WM signal, this paper use the mixed moments of the adaptive optimal kernel (AOK) time-frequency distribution to study the identification of multi-carrier modulation signals. Simulation results show that, this method can separate wavelet modulation signal from...
Wavelet modulation is a new type of multi-carrier modulation, this paper based on the asymptotically Gaussian distribution and frequency spectrum's feature of OFDM and wavelet modulated (WM) signal, studies the recognition of wavelet modulated signal in the additive white Gaussian noise channel. Using the joint estimation of the signal to noise ratio (SNR) and features value based on higher order...
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...
