LI Shuang-xia · Journal of Hangzhou Dianzi University · 2012
Wavelet packet modulation(WPM) is a new type of multi-carrier modulation.According to the non-linear and quadratic phase-coupling,this paper applies the theory of bispectrum analysis to the feature extraction and the parametric bispectrum estimation of wavelet packet modulation signal,and achieves the identification of wavelet packet modulation signal.Simulation results show that good performance is obtained.
