Underdetermined noisy blind separation using dual matching pursuits [PDF]
, 2004 Underdetermined blind source separation is a key application in audio where it is desirable to extract multiple sources from a stereo recording. A new variant on the stereo matching pursuit, the dual matching pursuit, is presented whereby independent ...

Separation of Communication Signals Based on Underdetermined Blind Source Separation [PDF]
Proceedings of the 2016 5th International Conference on Environment, Materials, Chemistry and Power Electronics, 2016 The paper proposes an improved underdetermined blind source separation (UBSS) method of nonlinear mixture, which can be applied to the communication signals' separation during data link transmission in the complicated electromagnetic environment. The proposed method combines the advantages of wavelet analysis and kernel canonical correlation analysis ...

Blind source separation of underdetermined mixtures of event-related sources [PDF]
Signal Processing, 2014 This paper addresses the problem of blind source separation for underdetermined mixtures (i.e., more sources than sensors) of event-related sources that include quasi-periodic sources (e.g., electrocardiogram (ECG)), sources with synchronized trials (e.g., event-related potentials (ERP)), and amplitude-variant sources.

EURASIP Journal on Audio, Speech, and Music Processing, 2006 We present a new technique for separating two speech signals from a single recording. The proposed method bridges the gap between underdetermined blind source separation techniques and those techniques that model the human auditory system, that is ...

Cryptanalysis of an Encryption Scheme Based on Blind Source Separation [PDF]
, 2006 Recently Lin et al. proposed a method of using the underdetermined BSS (blind source separation) problem to realize image and speech encryption. In this paper, we give a cryptanalysis of this BSS-based encryption and point out that it is not secure ...
