Auxiliary Function-Based Algorithm for Blind Extraction of a Moving Speaker
Jakub Janský, Zbyněk Koldovský, Jiří Málek +2
Recently, Constant Separating Vector (CSV) mixing model has been proposed for the Blind Source Extraction (BSE) of moving sources. In this paper, we experimentally verify the appli…
