Parametric and … WebThe higher-order cumulant and the higher-order cumulant spectrum have been widely used in engineering, and they are introduced in this section [34]. The higher-order spectrum can be defined as follows. Let {x (n)} be a real, discrete, zero-mean stationary process with a higher-order cumulant c k x = ...
WebAug 1, 2013 · Higher order spectra (also known as polyspectra) are defined as Fourier transform of the corresponding cumulant sequences. The conventional power spectrum is, in fact, the FT of the second-order cumulant. The third-order spectrum also called the bispectrum which is, by definition, the Fourier transform of the third-order cumulant. WebMay 18, 2024 · The high order spectrum based radar signal representation and the deep network based H-ELM recognition algorithm can well address the degrade recognition performance suffered by conventional methods due to he increasingly violent electronic confrontation and the emergence of new types of radar signals.
