Blind Capon Beamformer Based on Independent Component Extraction: Single-Parameter Algorithm,
Zbyněk Koldovský, Jaroslav Čmejla, Stephen O'Regan
We consider a phase-shift mixing model for linear sensor arrays in the context of blind source extraction. We derive a blind Capon beamformer that seeks the direction where the out…
Informed FastICA: Semi-Blind Minimum Variance Distortionless Beamformer
Zbyněk Koldovský, Jiří Málek, Jaroslav Čmejla +1
Non-Gaussianity-based Independent Vector Extraction leads to the famous one-unit FastICA/FastIVA algorithm when the likelihood function is optimized using an approximate Newton-Rap…
Dynamic Independent Component/Vector Analysis: Time-Variant Linear Mixtures Separable by Time-Invariant Beamformers
Zbyněk Koldovský, Václav Kautský, Petr Tichavský
A novel extension of Independent Component and Independent Vector Analysis for blind extraction/separation of one or several sources from time-varying mixtures is proposed. The mix…
