In this paper we present a solution to the discrete time nonlinear H-infiniti filtering problem using the recently developed information state approach. We show that the solution is, in general, infinite dimensional, and is expressed in terms of two dynamic programming equations: The first one describes the dynamics of the information state, and the second one provides a means for constructing the optimal filtering policy. The resulting filter depends on the time horizon length being considered. We show that in the linear systems case the solution is finite dimension, is independent of the time horizon length and has the familiar structure of linear H-infiniti filter.
