  • Abstract
    Owing to its bilinear nature, calculation of the Wigner-Ville distribution (WVD) produces crossterms between independent frequency components. Usually an averaging technique is adopted to smooth out these terms, the calculation time being proportional to the averaging times. Using the linear nature of averaging and Fourier transform (FT), this technique is improved resulting in a range saving of calculation time.
