Abstract: Automatic Modulation Recognition is considered significant in Communication Intelligence (COMINT) knowledge about the signal modulation type. The work at the output stage is concerned with information extraction, recording and exploitation and begins with signal demodulation that requires accurate modulation type. Recently many algorithms have been proposed to distinguish digitally modulated signals In this paper, we present and evaluate some problems related to automatic recognition of digital modulation signals by using maximum likelihood algorithm to find feature extraction and simulation by using statistical parameters on ASK,PSK,FSK,QAM and OFDM in presence of some Additive White Gaussian Noise (AWGN). Automatic Modulation Recognition of Communications Signals describes in depth by using artificial neural networks with pattern recognition for trained the digital modulation signals features and find efficiency with MSE. For performance and comparison, in this paper we present fuzzy logic for Adaptive Network Based Fuzzy Inference System (ANFIS) with Discrete Wavelet Transform (DWT).
