Blind separation of cyclostationary sources using joint block approximate diagonalization

Author(s): Dinh-Tuan Pham

Abstract

This paper introduces an extension of an earlier method of the author for separating stationary sources, based on the joint approximated diagonalization of interspectral matrices, to the case of cyclostationary sources, to take advantage of their cyclostationarity. the propose method is based on the joint block approximate diagonlization of cyclic interspectral density. An algorithm for this diagonalization is described. Some similation experiments are provided, showing the good performance of the method.
