I am trying to work on digital modulation classification using ANN the first step is to extract feature i have difficult on finding normalized centered instantaneous amplitude,phase and frequency to find the maximum value of Power Spectral Density (PSD) of normalized-centered instantaneous amplitude,phase and frequency using matlab can any one help me
