Spectral Determination of Nonlinear System Parameters

Spectral Determination of Nonlinear System Parameters

In this paper we propose an identification method of nonlinear system. This later can be structured by Wiener models. The determination of nonlinear system parameters can be done using spectral analysis. The system nonlinearity is allowed to be noninvertible general shape nonlinearity but it must be...
