Application of spectrum estimation of ARMA series basedon higher-order cumulant in fault diagnosis
Huang Shi-tao · 2004
In order to eliminate or attenuate the additive Gaussian colored noise in machine fault signals and obtain better power spectrum estimations, a method by using ARMA model based on higher-order cumulant for the data series is presented in the paper. The characteristic of higher-order cumulant is insensitive to Gaussian colored noise. The emulating results show that Gaussian colored noise can be effectively restrained by the method.
