Une généralisation de l'algorithme JADE

In the eld of blind source separation, joint-diagonalization based approaches constitute an important framework leading to useful algorithms among which the popular JADE algorithm. This latter algorithm is derived using only fourthorder cumulants. In this paper, we are mainly interested in generalizing the JADE's underlying contrast and its link with a joint-diagonalization criterion involving cumulants of any order greater or equal to three. The main interest is then to be able to choose the cumulants order or to combine statistical information of di erent orders.
