WebHigher Order Spectral (HOS) analysis is often applied e ectively to analyze many bio-medical signals to detect nonlinear and non-Gaussian processes. One of the most basic HOS methods is the bispectral estimation, which extracts the degree of quadratic phase coupling between individual frequency components of a nonlinear signal. Web4 de out. de 2024 · 3.0 HIGHER–ORDER SPECTRA. HOS are an increasingly used and valuable tool in identifying higher-order statistics that can predict the presence of nonlinearities. The present section provides a brief description of the HOS and their workings, for a more detailed description and derivation the reader is referred Refs 15–18.
