Abstract :
The Wigner-Ville distribution (WVD) is of great significance in time-frequency signal analysis. The authors present a new method of evaluating the WVD of a real signal using the fast Hartley transform (FHT). This is compared with the existing fast Fourier transform (FFT) method in terms of computation time. The FHT method presented turns out to be much faster than the FFT method.
