Blind Capon Beamformer Based on Independent Component Extraction: Single-Parameter Algorithm,
ZbynÄk Koldovský, Jaroslav Ämejla, 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
ZbynÄk Koldovský, JiÅà Málek, Jaroslav Ämejla +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…
