Wavelet bicoherence in matlab. 2 · 4 comments . Does decimation have an effect on noise (SNR)? submitted 4 years ago * by o0DrWurm0o. Let's say I've got an oversampled, band-limited signal. In the frequency domain, this results in my band-limited signal having lots of spectral wiggle room It is the purpose of this tutorial paper to place bispectrum estimation in a digital signal processing framework in order to aid engineers in grasping the utility of the available bispectrum 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. Such objects are used all the time. The mathematics is done in terms of quantum fields, which to some extent conceals what's going on. For example, your "(frequency-domain) coherence" is a correlation coefficient, which is normalized, whereas Physicists typically work in terms of correlation functions, which typically are not, but they largely amount to the same thing. The squared bicoherence in the nonredundant region has been estimated to demonstrate nonlinear coupling. The bicoherence values are minimal for white Gaussian noises (WGNs) and filtered noises. Higher bicoherence values in chaotic time series and normal background EEG activities are indicative of nonlinear coupling in these systems. The comodulation measure of neuronal oscillations with general harmonic wavelet bicoherence and application to sleep analysis Using the metric of harmonic wavelet bicoherence, MATLAB contour The bicoherence
