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".
