Blind Source Separation: a Partial Joint Diagonalization (pajod) Approach
نویسندگان
چکیده
Blind Separation of convolutive mixtures and Blind Equalization of Multiple-Input Multiple-Output (MIMO) channels are two different ways of naming the same problem, which we address here. A novel MIMO optimization criterion, subsequently presented in this paper, consists of a Partial Approximate Joint Diagonalization (PAJOD) of several matrices, containing some values of output cumulant multi-correlations. A numerical algorithm is then devised, which works block-wise, and sweeps all the output pairs.

Blind Separation of Convolutive Mixtures a Contrast-based Joint Diagonalization Approach
Blind Separation of convolutive mixtures and Blind Equalization of Multiple-Input Multiple-Output (MIMO) channels are two different ways of naming the same problem, which we address here. The numerical algorithm, subsequently presented in detail, is based on theoretical results on contrasts recently published by the authors [1]. This algorithm consists of Partial Approximate Joint Diagonalizati...
متن کاملJoint anti-diagonalization for blind source separation
We address the problem of blind source separation of non-stationary signals of which only instantaneous linear mixtures are observed. A blind source separation approach exploiting both auto-terms and cross-terms of the time-frequency (TF) distributions of the sources is considered. The approach is based on the simultaneous diagonalization and anti-diagonalization of spatial TF distribution matr...
متن کاملA Double Referenced Contrast for Blind Source Separation
This paper addresses the problem of blind source separation (BSS). To recover original signals, from linear instantaneous mixtures, we propose a new contrast function based on the use of a double referenced system. Our approach assumes statistical independence sources. The reference vectors will be incrusted in the cumulant to evaluate the independence. The estimation of the separating matrix w...
متن کاملA fast algorithm for joint diagonalization with application to blind source separation
We present a new approach to approximate joint diagonalization of a set of matrices. The main advantages of our method are computational efficiency and generality. The algorithm is based on the Frobeniusnorm formulation of the joint diagonalization problem, and addresses diagonalization with a general, non-orthogonal transformation. The iterative scheme of the algorithm inherits the key ideas f...
متن کاملBlind Signal Separation of Convolutive Mixtures: A Time-Domain Joint-Diagonalization Approach
We address the blind source separation (BSS) problem for the convolutive mixing case. Second-order statistical methods are employed assuming the source signals are non-stationary and possibly also non-white. The proposed algorithm is based on a joint-diagonalization approach, where we search for a single polynomial matrix that jointly diagonalizes a set of measured spatiotemporal correlation ma...
