Abstract

We consider a stationary process (with either discrete or continuous time)and find an adaptive approximating stationary process combining highquality approximation and other good propertiesthat can be interpretedas additional smoothness or small expense of energy. The problem is solvedin terms of spectral characteristics of the original process usingthe classical analytic methods of prediction theory.
