The Higher-Order Spectral Analysis Toolbox contains specialized tools for signal processing with higher-order spectra. The toolbox is an implementation of a wide range of higher-order spectral techniques, providing access to algorithms at the forefront of signal processing technology. Higher-order spectra, which are defined in terms of the cumulants or higher-order moments of a signal, contain additional information that isn't conveyed by the signal's autocorrelation or power spectrum. Higher-order spectra can suppress noise; identify nonmimum phase signals; extract information due to deviations from Gaussianity; and detect and characterize nonlinear properties in signals. Potential applications of higher-order spectral analysis include acoustics, biomedicine, econometrics, exploration seismology, nondestructive testing, oceanography, plasma physics, radar, sonar, and speech.
