Abstract: An important practical problem in the area of the higher-order statistical signal processing is to estimate the cumulants and polyspectra of the analyzed signal when a finite sequence of time samples is available. We cannot use the theoretical formula because they are based on the assumption that an infinite sequence of time samples is available, but this is not true in practice. In order to obtain a better estimate for bispectrum of the signal, different types of 2D window functions are used. Also, these windows are investigated in terms of the resolution and leakage effect of the indirect bispectrum estimate.
Keywords: higher-order statistics, bispectrum estimation, 2D window functions, bispectral resolution
