Abstract
A simplified way of deriving of realizable and explicit Wiener filters ispresented. Discrete time problems are discussed, in a polynomial equationframework. Optimal filters, predictors and smoothers are calculatedby means of spectral factorizations and linear polynomial equations. A newtool for obtaining these equations, for a given problem structure, is described.It is based on evaluation of orthogonality in the frequency domain,by means of cancelling stable poles with zeros.
