Abstract

This paper deals with nonlinear Blind Source Separation (BSS) applied to a simple bijective "toy" model. Our objective is to better understand the difficulties encountered in nonlinear BSS, especially when estimating the parameters of mixing or separating structures. The results of this study and the proposed solutions may then be used by the BSS researchers dealing with actual nonlinear physical models. The simulation results confirm the usefulness of our proposed solutions.
