Abstract :
In this paper we derive algebraic algorithms for the blind extraction of Constant Modulus source signals from convolutive mixtures. In the single-channel case the equalizer follows from the best rank-1 approximation of a fourth-order tensor. In the multi-channel case we consider the case of paraunitary mixtures. The solution can then be obtained by means of a simultaneous matrix decomposition.
