The Fourier Transform (FT) is the well-known classical representation of signals components by providing the frequency analysis representations of the signals. The Fourier transformation is found with some determinant such as signal dependent transforming, in another word, [15] the FT is helpful with only particular types of signals such as the pseudo-stationary signals and stationary signals, whereas the FT is not fulfilling the expectations while it
