Independent Component Analysis, Contrasts, and Convolutive Mixtures

چکیده
The paper is organized as follows. Section 1 states the problem, assumptions, and notations, and includes a brief partial bibliographical survey. Section 2 is a reminder about whitening operations and cumulants. Section 3 defines a wide class of contrast functionals and gives several examples; some of them are new. Practical algorithms are presented in section 4. The effect of a carrier frequency offset is analyzed in section 5. Eventually, specific tools are proposed in section 6, when transmitted signals are discrete. IMA Conf. Mathematics in Communications II, Lancaster University, UK, 16-18 Dec 2002

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 کاملAn automatic method for separation and identification of Biomedical Signals from Convolutive Mixtures by Independent Component Analysis in the Frequency Domain
In this study we propose an automatic method for solving convolutive mixtures separation. The independent components are extracted by frequency domain analysis, where the convolutive model can be solved by instantaneous mixing model approach. The signals are reconstructed back in the observation space resolving the ICA model ambiguities. Simulations are carried out to test the validity of the p...
متن کاملModel Structure Selection in Convolutive Mixtures
The CICAAR algorithm (convolutive independent component analysis with an auto-regressive inverse model) allows separation of white (i.i.d) source signals from convolutive mixtures. We introduce a source color model as a simple extension to the CICAAR which allows for a more parsimoneous representation in many practical mixtures. The new filter-CICAAR allows Bayesian model selection and can help...
متن کاملConvolutive independent component analysis by leave-one-out optimal kernel approximation
This work addresses on blind separation of convolutive mixtures of independent sources. The temporally convolutive structure is assumed to be composed of multiple mixing matrices, each corresponding to a time delay, collectively transforming a segment of consecutive source signals to form multichannel observations. As τ = 1, this problem reduces to linear independent component analysis. For arb...

متن کاملBlind Source Separation of Convolutive Mixtures of Speech in Frequency Domain
This paper overviews a total solution for frequencydomain blind source separation (BSS) of convolutive mixtures of audio signals, especially speech. Frequency-domain BSS performs independent component analysis (ICA) in each frequency bin, and this is more efficient than time-domain BSS. We describe a sophisticated total solution for frequency-domain BSS, including permutation, scaling, circular...
