High order spectral analysis
WebAug 1, 2013 · The advantages of using high order spectral analysis can be summarised as follows [12]: (1) If the measurement x(n) is Gaussian, the cumulants C m x(n)=0 for m>2. … WebAbstract Higher 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.

WebMay 1, 2009 · HOS are used in the analysis and interpretation of signals from nonlinear systems. The development and utilisation of the fast Fourier transform (FFT), enables one to reveal information regarding the distribution of energy among a signal's frequency components. The power spectrum is regarded as the decomposition of a signal's power.

Bispectrum and bicoherence may be applied to the case of non-linear interactions of a continuous spectrum of propagating waves in one dimension. Bispectral measurements have been carried out for EEG signals monitoring. It was also shown that bispectra characterize differences between families of musical instruments. In seismology, signals rarely have adequate duration for making sensible bispectral estimates fr… WebDec 31, 1992 · Higher-Order Spectra Analysis: A Nonlinear Signal Processing Framework.
