PCT No. PCT/FR90/00932 Sec. 371 Date Jul. 8, 1992 Sec. 102(e) Date Jul. 8, 1992 PCT Filed Dec. 20, 1990 PCT Pub. No. WO91/11037 PCT Pub. Date Jul. 25, 1991.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(1), Q(2), . . . Q(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".
