Abstract

Some properties of the XFT as a discrete fractional Fourier transform and as a linear canonical transform are given in this chapter. The eigenvectors of the discrete fractional Fourier transform are obtained and the discrete canonical coherent states are studied. An algorithm to compute a fast linear canonical transform and an application to digital steganography are also given.
