Stochastic and Deterministic Tensorization for Blind Signal Separation [PDF]

open access: yesLatent Variable Analysis and Signal Separation, 2015
Given an instantaneous mixture of some source signals, the blind signal separation BSS problem consists of the identification of both the mixing matrix and the original sources. By itself, it is a non-unique matrix factorization problem, while unique solutions can be obtained by imposing additional assumptions such as statistical independence.

Towards interpretable classifiers with blind signal separation [PDF]

open access: yesThe 2012 International Joint Conference on Neural Networks (IJCNN), 2012
Blind signal separation (BSS) is a powerful tool to open-up complex signals into component sources that are often interpretable. However, BSS methods are generally unsupervised, therefore the assignment of class membership from the elements of the mixing matrix may be sub-optimal.

Performing Nonlinear Blind Source Separation With Signal Invariants [PDF]

open access: green, 2009
Given a time series of multicomponent measurements x(t), the usual objective of nonlinear blind source separation (BSS) is to find a "source" time series s(t), comprised of statistically independent combinations of the measured components. In this paper,

Relevance of polynomial matrix decompositions to broadband blind signal separation [PDF]

open access: yesSignal Processing, 2017
The polynomial matrix EVD (PEVD) is an extension of the conventional eigenvalue decomposition (EVD) to polynomial matrices. The purpose of this article is to provide a review of the theoretical foundations of the PEVD and to highlight practical ...

Accelerated Conjugate Gradient for Second-Order Blind Signal Separation

open access: yesAcoustics, 2022
This paper proposes a new adaptive algorithm for the second-order blind signal separation (BSS) problem with convolutive mixtures by utilising a combination of an accelerated gradient and a conjugate gradient method.

Blind source separation algorithm for complex signals in noise

open access: yesDianzi Jishu Yingyong, 2022
Complex signal analysis is one of the common problems in signal processing technology. In blind signal separation technology, especially convolution mixing problem or frequency domain analysis, it is necessary to establish the corresponding complex value

JCCM: Joint conformer and CNN model for overlapping radio signals recognition

open access: yesElectronics Letters, 2023
Overlapping radio signals recognition is attracting more attention as the development and ubiquitous application of radio technologies. The traditional blind signal separation (BSS) method is mostly not effective when both radio propagation effects and ...
