Optimal White Noise Estimators Based on Kalman Filtering for Systems with Correlated Noises

Based on the Kalman filtering,the unified white noise estimators are presented for time-invariant systems with correlated noises.They consist of input white noise estimators and measurement white noise estimators,and can handle the white noise filtering, smoothing and prediction problems in a unified framework.They can be applied to signal processing in oil seismic exploration,and state estimation.A simulation example for Bernoulli-Gaussian white noise smoother shows their effectiveness.
