A new Wigner-Ville Distribution (WVD) estimation is proposed. This improved and efficient WVD is based on Signal Decomposition (SD) by DCT or DFT Harmonic Wavelet Transform (DCTHWT or DFTHWT) and the Modified Magnitude Group Delay (MMGD). The MMGD processing can be either in fullband or subband. The SD by DCTHWT provides better quality low leakage decimated subband components. The concatenation of WVDs of the subbands results in an overall WVD, significantly free from crossterms and Gibbs… CONTINUE READING
