Abstract :
Kalman filtering has been suggested as a method for the design of equalizers for communication channels with intersymbol interference, and additive random receiver noise. This is possible because a state space structure of the channel model can be constructed. It is appropriate if the noise is truly white, and the finite impulse response model describing the intersymbol interference is short. If the receiver noise is completely arbitrary, except that it has bounded energy, then an H infinity design may be more appropriate, since it is designed to meet these conditions, with a performance guarantee under the worst case situation. An H infinity design can be of full order or reduced order. In this paper we consider the full order case only. The design is not in a stochastic setting, but rather allows one to design for unknown, and possibly very bad disturbances
