The wavelet transform for signal analysis was promoted to research of the non-classical quantum properties of the photon-added coherent state by means of quantum transformation theory and the technique of integration within an ordered product of operators. The result shows that the wavelet transform spectra of the photon-added coherent states not only exhibits the common behaviors, which are characteristics of the wavelet transformation, but also disappears its symmetry and arises some new crests gradually with the increasing value of the number of added photons.
