Wavelet-based Identification of Digital Modulation Signals
Mingjun Shi · Radio Engineering of China · 2010
The wavelet transform is used for detecting transient signals and extracting time-frequency characters in digital modulation signals.The approach is based on the ability of multiscale analysis of wavelet transform.We propose a suitable method for distinguishing MASK signal,MFSK signal,MPSK signal and MQAM signal without any pre-knowledge.The simulation results show that the method is reasonable and can perform well.
