    Abstract: Method and device for real-time separation of signals received by a predetermined number of sensors, the mixture being linear. The signals received are firstly decorrelated [s(t)], and they are then introduced into a rotator which calculates, through a succession of elementary rotations [Q.sup.(1), Q.sup.(2), . . . Q.sup.(m) ], the orthogonal matrix (Q) making it possible to recover the independent source-signals [x(t)] by multiplication (F) of this matrix (Q) by the decorrelated input signals [s(t)]. The identification of (Q) is based on the estimation of statistical magnitudes called "cumulants".

    Abstract: A method for the blind identification of sources within a system having P sources and N receivers comprises at least one step for the identification of the matrix of the direction vectors of the sources from the information proper to the direction vectors ap of the sources contained redundantly in the m=2q order circular statistics of the vector of the observations received by the N receivers. Application to a communications network.
