Automatic Classification of Digital Modulated Types Based on the Combination of Instantaneous Amplitude and Wavelet Transform

()

Abstract:

A new algorithm based on the combination of instantaneous amplitude of signal and wavelet transform is proposed for automatic identification of digital modulated signals.This algorithm is featured by simple computation and real time processing. The 2ASK,4ASK,2FSK,4FSK and 2PSK signals are classified successfully.Simulation results show the accuracy of the algorithm.
