| Abstract: | This paper first introduces Wigner-Ville distribution and its application in time-Frequency Analysis,and the simulation result of WVD is implemented by ADSP21160 based on its property.The simulation result shows that Wigner-Ville distribution of signal can be used to estimate the instantaneous frequency of signal because of its suitability for non-stationary linear frequency-modulated signal. |
