CROSS-TERM ANALYSIS OF LNL MODELS

This brief proposes a method called cross-term analysis to analyze the structure of the class of LNL models, those which consist of a memory less nonlinearity sandwiched between two linear systems, By evaluating a family of conditional expectations, cross-term analysis unambiguous ly determines the cross relations among all delay elements, A byproduc t of this methodology is a way to determine the lengths of the two lin ear subsystems in the LNL model, The method is independent of the degr ee of nonlinearity of the static subsystem.
