High order cumulant
WebHigh-order cumulant is a new signal processing technology, which has the advantages of suppressing Gaussian colored noise and extracting phase information ( Shao et al., 2008; … WebApr 4, 2024 · Higher order statistics (HOS) are meant for nonlinear signal processing, dealing with signals from nonlinear systems. They are used to extract information from random signals. Second order statistics like autocorrelation function and probability density function are used only for linear signals such as Gaussian noise.
