8 The DUET Blind Source Separation
This chapter presents a tutorial on the DUET Blind Source Separation method which can separate any number of sources using only two mixtures. The method is valid when sources are W-disjoint orthogonal, that is, when the supports of the windowed Fourier transform of the signals in the mixture are disjoint. For anechoic mixtures of attenuated and delayed sources, the method allows one to estimate...
متن کاملPhase Aliasing Correction For Robust Blind Source Separation Using DUET
Degenerate Unmixing Estimation Technique (DUET) is a technique for blind source separation (BSS). Unlike the ICA based BSS techniques, DUET is a time-frequency scheme that relies on the socalled W-disjoint orthogonality (WDO) property of the source signals, which states that the windowed Fourier transforms of different source signals have statistically disjoint supports. In addition to being co...
متن کامل: a Blind Source Separation Technique
| Separation of sources consists in 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: the linear mixture should bèblindly' processed. This typically occurs in narrow-band array processing applications when the array manifold is unknown or distorted. This paper introduces a new sour...
متن کاملFetal ECG Extraction by Combining Single-Channel SVD and Cyclostationarity-Based Blind Source Separation
Fetal Electrocardiogram (FECG) can provide important clinical information for the assessment of fetal well-being. However, the extraction of FECG from the maternal abdominal wall remains an open problem due to various kinds of interferences and noises, where the maternal Electrocardiogram (MECG) is the dominant source of interference. In this study, a novel FECG extraction framework by combinin...
متن کاملSource Number Estimation and Clustering for Underdetermined Blind Source Separation
Much research has been undertaken in the field of blind source separation (BSS) and a large number of algorithms have been developed. However, most of them assume that the number of sources is known. In this paper we present an algorithm to estimate the number of sources in the (over-)determined and underdetermined case. We call this algorithm NOSET (Number of Sources Estimation Technique). We ...
