We exhibit a canonical basis φ of eigenvectors for the discrete Fourier transform (DFT). The transition matrix ⊖ from the standard basis to φ defi006Ees a novel transform which we call the discrete oscillator transform (DOT for short). Finally, we describe a fast algorithm for computing ⊖ in certain cases. copyright by EURASIP.
