Higher-order spectral analysis

Web1 de out. de 2024 · Higher-order spectral analysis-based trispectrum (TS) TS is a type of higher-order spectral analysis method for obtaining information on the 3-D Fourier transform of the fourth-order cumulant function [58]. The benefit of the TS method over the PS method is the former’s ability to analyze nonstationary and nonlinear signals in … WebThe higher-order spectrum is an extension Fourier spectrum that uses higher moments for spectral estimates. This essentially nullifies all Gaussian random effects, therefore, can reveal non-Gaussian and nonlinear characteristics in the complex patterns of EEG time series. The paper demonstrates the distinguishing features of bispectral analysis ...
