Applying Wavelet Transform to the Suppression of the Interference-terms of Wigner-Ville Distribution
Fu Hai · Journal of Xi'an Petroleum Institute · 2001
Wingner Ville distribution has good time frequency characteristic. Its interference terms are oscillatory at high frequency. But after Wigner Ville distribution of a signal is decomposed and reconstructed by 2D tensor product wavelet analysis, the interference terms can be suppressed. The method is stated in detail. And an example is presented for illustrating the application of it. The result of the example shows that the method is very effective.
