Cramér-Rao bound for this  model is derived and the extended algorithm is shown to be  asymptotically efficient if score functions of the signals are  known in each block. In contrast to classical ICA algorithms, the  proposed method is able to profit from varying distribution of the  original signals as well as from their non-stationarity, which is  demonstrated on simulations with real-world signals.</abstract> <abstract language="cze" primary="0">V práci je navrženo zobecnění algoritmu EFICA pro slepou separaci po částech stacionárních negaussovských zdrojů. Navržená metoda využívá jak různosti pravděpodobnostního rozložení separovaných signálů v jednotlivých časových intervalech, tak proměnlivosti jejich variance. Přesnost separace dosahuje příslušné Rao-Cramerovy meze za předpokladu, že variance signálů je stejná na všech intervalech.</abstract>  <action target="WRD"> <ARLID>cav_un_auth*0238885</ARLID> <name>ICASSP 2008, IEEE International Conference on Acoustics, Speech adn Signal Processing</name> <place>Las Vegas</place> <dates>30.03.2008-04.04.2008</dates>  <country>US</country> </action>    <reportyear>2010</reportyear>  <RIV>BB</RIV>      <permalink>http://hdl.handle.net/11104/0004578</permalink>       <arlyear>2008</arlyear>       <unknown tag="mrcbU56"> textový dokument 150kB </unknown> <unknown tag="mrcbU63"> cav_un_epca*0306559 ICASSP 2008: IEEE International Conference on Acoustics, Speech, and Signal Processing 978-1-4244-1483-3 1913 1916 Bryan Conference Management Services 2008 </unknown> </cas_special> </bibitem>
