A blind source separation technique using second-order statistics

- A. Belouchrani, K. Abed-Meraim, Jean-François Cardoso, E. Moulines
- Computer Science, Mathematics
- IEEE Trans. Signal Process.
- 1 February 1997

Separation of sources consists of recovering a set of signals of which only instantaneous linear mixtures are observed. In many situations, no a priori information on the mixing matrix is available:… Expand

Blind source separation based on time-frequency signal representations

- A. Belouchrani, M. Amin
- Mathematics, Computer Science
- IEEE Trans. Signal Process.
- 1 November 1998

Blind source separation consists of recovering a set of signals of which only instantaneous linear mixtures are observed. Thus far, this problem has been solved using statistical information… Expand

Underdetermined Blind Separation of Nondisjoint Sources in the Time-Frequency Domain

- A. Aïssa-El-Bey, N. Linh-Trung, K. Abed-Meraim, A. Belouchrani, Y. Grenier
- Mathematics, Computer Science
- IEEE Transactions on Signal Processing
- 1 March 2007

This paper considers the blind separation of nonstationary sources in the underdetermined case, when there are more sources than sensors. A general framework for this problem is to work on sources… Expand

Separating More Sources Than Sensors Using Time-Frequency Distributions

- Nguyen Linh-Trung, A. Belouchrani, K. Abed-Meraim, B. Boashash
- Computer Science, Mathematics
- EURASIP J. Adv. Signal Process.
- 2005

We examine the problem of blind separation of nonstationary sources in the underdetermined case, where there are more sources than sensors. Since time-frequency (TF) signal processing provides… Expand

Robust whitening procedure in blind source separation context

- A. Belouchrani, A. Cichocki
- Mathematics
- 23 November 2000

An efficient algorithm is presented for robust whitening in the presence of temporally uncorrelated additive noise that may be spatially correlated. This whitening is introduced as a pre-processing… Expand

Second Order Blind Separation of Temporally Correlated Sources

- A. Belouchrani, K. Abed-Meraim, Jean-François Cardoso, E. Moulines
- Mathematics
- 1993

Blind separation of sources consists in recovering a set of statistically independent signals whose only mixtures are observed. Such instantaneous mixtures occur in narrow band array data which can… Expand
