Abstract

In this paper

a new efficient method of feature extraction and combined classification based on wavelet analysis and fuzzy integral is presented in order to identify modulation types of communication signals

which are non-stable and varied in wide range of signal noise ratio (SNR).Accuracy and efficiency of identification are obviously improved.The result of computer simulation has proved its good performance
