The exact computation of a general multivariate Wiener-Kolmogorov filter is usually done in state-space form. This paper develops a new method to solve the problem within the polynomial framework. To do so, several matrix polynomial techniques are used. To obtain the initial values, some new techniques are also developed. Finally, some extensions and applications are outlined.
