This paper, gives a general framework to investigate the existence and the general structure of causal inverse filters for multiple-input multiple-output (MIMO) systems with intersymbol interference (ISI). It gives necessary and sufficient conditions for the existence of causal and stable inverse filters allowing for further properties of the receive filters such as stability and smoothness of its transfer function. Furthermore, a parametrization and the general structure of all causal inverses is given.
