Resum
A general class of higher-order moments- and spectra-based time-frequency distributions, including Wigner higher-order moment spectra (WHOS), has been defined and studied recently as an extension of bilinear time-frequency representations (TFR) in terms of multilinear (higher than two) moments of the signal. In this paper, the analysis of mono- and multi-component signals is addressed using higher-order TFR. A computationally feasible implementation of the Wigner bispectrum and trispectrum (i.e....
