Performance analysis of blind signal separation methods based on asymmetric contrast functions

In this paper, we consider the blind signal separation problem in the convolutive case. More precisely, we present a generalization of classical contrast functions to more flexible asymmetric forms and give examples of these new criteria. We also realize a statistical study of the proposed source separation approach, including both the consistency and the asymptotic normality aspects.
