Abstract :
A fast algorithm for computing the pseudo-Wigner distribution using the fast Hartley transform (FHT) is presented. Unlike the conventional fast Fourier transform (FFT) approach, this algorithm performs entirely in the real domain. Many efficient FHT algorithms can be applied, and the computation complexity is reduced from three complex FFTs to three real FHTs
