Abstract: Many practically important linear systems are slowly time--varying. In this paper we consider the frequency--domain identification of slowly time--varying systems with limited impulse response (underspread systems). We review time--frequency representations of LTV systems and its connection to the Gabor expansion of signals. It is shown how the matched multiwindow Gabor expansion can be used for the optimum frequency--domain identification and canonical realization of underspread LTV systems.... (Update)
