【Abstract】 Unifying and universal optimal white noise estimators are presented for the time_varying systems with the correlated noises, including the measurement white noise estimators and input white noise estimators. Unifying fixed point and fixed_interval optimal white noise smoothers are presented. And specially, unifying steady state white noise estimators are also presented for time invariant systems. They provide a new way to solve the problems of the state or signal estimation and deconvolution, and can be applied to data processing in oil exploration. A simulation example for Bernoulli_Gaussian white noise is given to show the effectiveness of those estimators.更多还原
