Root high-order cumulant music
WebDue to the absence of finite second-order moments in impulse noise, conventional higher-order cumulant algorithms cannot be used. For the purpose of direction finding under impulse noise, in the literature [ 20 ], a theory based on fractional lower-order statistics (FLOS) was first proposed. WebThe polynomial rooting implementation of the high-order cumulant based multiple signal classification (MUSIC) methods are then investigated, concentrating on the direction-of …

WebHigher order cumulants of conserved quan-tities such as the net-baryon, net-charge, and net-strangeness numbers, as a function of beam energy, are expected to show non-monotonic behaviour near the critical point [14, 15]. Near the QCD critical point, the third order cumulant (or skewness) and fourth order cumulant (or kurtosis) of net-baryon ...

WebHigher order spectra (also known as polyspectra), defined in terms of higher order statistics (“cumulants”) of a signal, do contain such information. Particular cases of higher order spectra are the third-order spec- trum also called the bispectrum which is, by definition, the Fourier transform of the third-order statistics, and Weborder cumulant-based covariance matrix for its good performance in low SNR scenario as well as root-MUSIC’s computational efficiency. In the present work, our focus is to …
Web1 Jun 2015 · Then it utilizes the root-MUSIC method to yield the DOA estimates. In [27], a higher-order cumulant MUSIC algorithm has been developed. This scheme can correctly work for the underdetermined case where the number of signals is larger than the number of sensors, but it is unable to handle the coherent signals. Webhave Taylor expansions about ξ = 0 up to order four only. The normal distribution N(µ,σ2) has cumulant generating function ξµ+ ξ2σ2/2, a quadratic polynomial implying that all cumulants of order three and higher are zero. Marcinkiewicz (1935) showed that the normal dis-tribution is the only distribution whose cumulant generating function ...
WebDefinitions. The Fourier transform of the second-order cumulant, i.e., the autocorrelation function, is the traditional power spectrum.. The Fourier transform of C 3 (t 1, t 2) (third-order cumulant-generating function) is called the bispectrum or bispectral density.. Calculation. Applying the convolution theorem allows fast calculation of the bispectrum: (,) = () (+), …
Weborder cumulants of multidimensional data. Since the dth order cumulant can be presented in the form of an d-dimensional tensor, the algorithm is presented using tensor operations.
