Filtering, smoothing, and prediction have become key tools of statistical signal, image, and speech processing and found applications in algorithms of various electronic systems. Estimation can be provided using methods of finite impulse response (FIR) linear optimal filtering having strong features, such as the inherent bounded input/bounded output stability and robustness against temporary model uncertainties and round-off errors. In this talk, I will show that the general p-shift optimal linear FIR estimator follows straightforwardly from the real discrete-time state space model (from n and n-1 to n) used in signal processing, rather than from the prediction one (from n to n+1) used in control. This general estimator allows solving universally the problems of filtering (p 0), prediction (p > 0), and smoothing (p < 0) on a horizon of N points. I will then present different batch and recursive algorithms and give an analysis of the estimation errors along with the noise power gain. Applications will be given for polynomial state space modeling, clock state estimation and synchronization, and image processing.
