Abstract :
This paper addresses the problem of tracking of time-varying mobile radio channels with time-varying parameters, and the channels are modeled as auto-regressive (AR) models. A polynomial H-infinity channel filter in Krein space is designed for the tracking problem. With the help of an ARMA innovation model, the solution to the tracking problem can be obtained. The H-infinity channel estimators are calculated by performing one J-spectral factorization
