In this letter, we consider the problem of simultaneous blind signal extraction of arbitrary group sources from a rather large number of observations. Amari (2000) proposed a gradient algorithm that optimizes the maximum-likelihood (ML) criteria on the Stiefel manifold and solves the problem when the approximate (or hypothetical) densities of the desired(More)
In this paper a novel constrained-stability least-mean-squares (LMS) algorithm for filtering speech sounds is proposed in the adaptive noise cancellation (ANC) problem. It is based on the minimization of the squared Euclidean norm of the weight vector change under a stability constraint over the a posteriori estimation errors. To this purpose, the(More)
