Underdetermined Blind Source Separation of Temporomandibular Joint Sounds [PDF]

open access: yesIEEE Transactions on Biomedical Engineering, 2006
The underdetermined blind source separation problem using a filtering approach is addressed. An extension of the FastICA algorithm is devised which exploits the disparity in the kurtoses of the underlying sources to estimate the mixing matrix and thereafter achieves source recovery by employing the ll-norm algorithm.

Underdetermined Convolutive Blind Source Separation via Time–Frequency Masking [PDF]

open access: yesIEEE Transactions on Audio, Speech, and Language Processing, 2010
In this paper, we consider the problem of separation of unknown number of sources from their underdetermined convolutive mixtures via time-frequency (TF) masking. We propose two algorithms, one for the estimation of the masks which are to be applied to the mixture in the TF domain for the separation of signals in the frequency domain, and the other for

Rolling Bearing Fault Diagnosis Based on Nonlinear Underdetermined Blind Source Separation

open access: yesMachines, 2022
One challenge of bearing fault diagnosis is that the vibration signals are often a nonlinear mixture of unknown source signals. In addition, the practical installation position also limits the number of observed signals. Hence, bearing fault diagnosis is

Underdetermined Blind Source Separation Based on Subspace Representation [PDF]

open access: yesIEEE Transactions on Signal Processing, 2009
This paper considers the problem of blindly separating sub- and super-Gaussian sources from underdetermined mixtures. The underlying sources are assumed to be composed of two orthogonal components: one lying in the rowspace and the other in the nullspace of a mixing matrix. The mapping from the rowspace component to the mixtures by the mixing matrix is

Blind separation of underdetermined mixtures with additive white and pink noises [PDF]

open access: yes, 2014
This paper presents an approach for underdetermined blind source separation in the case of additive Gaussian white noise and pink noise. Likewise, the proposed approach is applicable in the case of separating I + 3 sources from I mixtures with additive
