Abstract :
In this paper we develop a method for identifying Wiener-type nonlinear systems, that is, systems consisting of a linear dynamic system followed by a static nonlinearity. Unlike previous techniques developed for Wiener system identification, our approach allows the identification of systems with noninvertible, but known, nonlinearities
