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 ], and they are then introduced into a rotator which calculates , through a succession of elementary rotations , q . sup ., . . . q . sup . ], the orthogonal matrix making it possible to recover the independent source - signals ] by multiplication of this matrix by the decorrelated input signals ]. the identification of is based on the estimation of statistical magnitudes called &# 34 ; cumulants &# 34 ;.
