....of Scientific Research grant F49620 99 1 0034 P00002. Actually, the problem is a special case of the generalized eigenvector problem with non negative definite matrices; hence, it is more properly viewed as a generalized singular value problem. using second order statistics is well known [7, 8], but the connection to MNF is not; in fact, the MNF algorithm itself does not seem to be widely known. The purpose of this paper is twofold: We will review MNF, then show that the variational problem produced will also yield independent components in the sense that we will implicitly compute the ....

....(HOS) Keywords: Blind Separation of Sources, ICA, PDF, Geometrical Methods, Decorrelation, Cholesky Factorization, Orthogonalization and Whitening process. 1 Introduction The blind separation of sources (BSS) is a recent and important problem in signal processing and it has many applications [1]. Since 1984 [2] it has been studied by many authors whilst many algorithms have been proposed. The blind separation of sources problem consists in retrieving unknown sources X(t) from only observing a mixture of them Y (t) 3, 4] see Fig. 1) In general case, authors assume that the sources are ....
....the covariance matrix of the mixing signals [21, 22] In the following, we consider only the case of instantaneous mixture with same number p of sources and sensors. On the other hand, it is known that the separation of instantaneous mixture can be achieved up to a permutation and a scale factor [5, 1] (i.e. the estimated sources S(t) are equal to the sources up to a permutation and a scale factor) Therefore the global matrix G = WM (W is the demixing matrix or the separating matrix) should satisfy the following: G = PD (1) where P is any permutation and D is any full rank diagonal matrix. ....
