Self-stabilized gradient algorithms for blind source separation with orthogonality constraints
Recently, developments in self-stabilized algorithms for gradient adaptation of orthonormal matrices have resulted in simple but powerful principal and minor subspace analysis methods. In this paper, we extend these ideas to develop algorithms for instantaneous prewhitened blind separation of homogeneous signal mixtures. Our algorithms are proven to be self-stabilizing to the Stiefel manifold o...
متن کاملA Neural Network for the Blind Separation of Non-Gaussian Sources
| In this paper, a two{layer neural network is presented that organizes itself to perform blind source separation. The inputs to the network are prewhitened linear mixtures of unknown independent source signals. An unsu-pervised nonlinear hebbian learning rule is used for training the network. After convergence, the network is able to extract the source signals from the mixtures, provided that ...
متن کاملA new non-orthogonal approximate joint diagonalization algorithm for blind source separation
A new algorithm for approximate joint diagonalization of a set of matrices is presented. Using a weighted leastsquares (WLS) criterion, without the orthogonality constraint, it is compared with an analoguous algorithm for blind source separation (BSS). The criterion of our algorithm is on the separating matrix while the other is on the mixing matrix. The convergence of our algorithm is proved u...
متن کاملBlind Source Separation Algorithms with Matrix Constraints
In many applications of Independent Component Analysis (ICA) and Blind Source Separation (BSS) estimated sources signals and the mixing or separating matrices have some special structure or some constraints are imposed for the matrices such as symmetries, orthogonality, non-negativity, sparseness and specified invariant norm of the separating matrix. In this paper we present several algorithms ...
متن کاملBlind source separation of instantaneous MIMO systems based on the least-squares Constant Modulus Algorithm
Blind symbol detection for mobile communications systems has been widely studied and can be implemented by using either adaptive or iterative techniques. However, adaptive blind algorithms require data of sufficient length to converge. Therefore, in a rapidly changing environment, they are likely unable to track the changing channels. In such a situation, one possible solution is to use iterati...
