Abstract

This article concerns the linearization of a nonlinear system by connecting a nonlinear Volterra prefilter tandemly with the nonlinear system and by adaptively adjusting the coefficients of the prefilter. “A nonlinear filtered-x LMS algorithm” for updating the coefficients of a nonlinear prefilter, as proposed, is shown to be viewed as an extension of the well-known filtered-x LMS algorithm
