High order spectral analysis
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… WebFind many great new & used options and get the best deals for Spectral and High Order Methods for Partial Differential Equations ICOSAHOM at the best online prices at eBay!

WebMar 1, 1994 · HOS consist of higher-order moment spectra, which are defined for deterministic signals, and cumulant spectra, which are defined for random processes. In general there are three motivations behind the use of HOS analysis in signal processing: • to suppress Gaussian noise of unknown mean and vari ance in detection and parameter … WebNov 1, 2006 · Even though higher-order spectral analysis is by now a mature field, complex signals are still not routinely used, as they are in second-order analysis. The reason is the complexity of the complex case: nth order moment functions of a complex signal can be defined in 2 n different ways, depending on the placement of complex conjugate operators.
