In this paper, we address the problem of the blind separation of convolutive mixtures of sources also known as blind equalization of linear time invariant multi-input multi-output systems in digital communications. In our case, the considered input signals are cyclo-stationary processes whose cyclic frequencies are not necessarily known. To tackle that problem, we propose to use a new algorithm that...
This paper addresses the problem of the non-unitary joint block diagonalization (NU - JBD) of a given set of matrices. Such a problem arises in various fields of applications among which blind separation of convolutive mixtures of sources and array processing for wide-band signals. We present two new algorithms based respectively on (absolute) gradient and relative gradient descendent approaches....
