COMPARAISON DES PERFORMANCES DE PLUSIEURS METHODES DE SEPARATION AVEUGLE DE SOURCES AUX ORDRES SUPERIEURS

Over the last decade, higher order (HO) blind source separation methods have been strongly developed. More recently, some results about the behaviour of some of these methods in the presence of sources typical of the radiocommunications field have been described. The purpose of this paper is to present a comparative overview of the performance of four HO blind source separation methods in both radiocommunications and radar contexts. maniere parametrique et pour differentes situations representatives du contexte des radiocommunications, les performances de la methode JADE ou les matrices propres de la quadricovariance sont ponderees, non plus par les valeurs propres associees, mais par les racines carrees de celles-ci. Cette methode est notee J1 dans la suite. Dans un second temps, les methode J1, J2, C1 et C2 sont comparees sur signaux synthetiques empruntes aux contextes aussi bien des radiocommunications que du radar.
