Abstract :
The problem of minimum mean-square interpolation of discrete time stationary stochastic processes using a system consisting of a finite number p of nonlinear instantaneous transformations followed by a p input-one output infinite extent linear filter is studied. The expressions of the optimal interpolator and of the approximation error are derived and generalize the corresponding relations known in linear interpolation theory. Some extensions, including the estimation problem with several missing observations, are also investigated
