Filtering and parameter estimation in a simple linear system driven by a fractional Brownian motion

Abstract

The optimal filter is derived in a Gaussian linear system where the signal is a fixed random variable and the observation is driven by a fractional Brownian motion. An application to a related parameter estimation problem is discussed and a Girsanov-type formula is investigated.
