A new family of methods, named 2q-ORBIT (q > 1), is proposed in this paper in order to blindly identify potentially underdetermined mixtures of statistically independent sources. These methods are based on the canonical decomposition of q-th order (q ges 2) cumulants. The latter decomposition is brought back to the decomposition of a third order array(More)
In this paper, we consider the problem of blind separation of DS-CDMA signals, from convolutive mixtures received by an antenna array. We suppose that multi-path reflections occur in the far-field of this array and that intersymbol-interference is caused by large delay spread. Our receiver is deterministic and relies on a third-order tensor decomposition,(More)
In this paper, we present a technique for the blind separation of DS-CDMA signals received on an antenna array, for a multi-path propagation scenario that generates inter-symbol-interference. Our method relies on a new third-order tensor decomposition, which is a generalization of the parallel factor model. We start from the observation that the temporal,(More)
