A new signal separation technique using double referenced system

This paper addresses the problem of blind source separation (BSS). To recover original signals, from linear instantaneous mixtures, we propose a new separation technique based on the use of a double referenced system. The reference signals will be incrusted in the cumulant to evaluate the statistical independence between sources. The non-orthogonal joint diagonalization of a set of referenced cumulant matrices gives an estimation of the separating matrix. The important advantage of our proposed technique is the high separation quality in noisy environment by an appropriate choice of reference signals. Computer simulations are presented to illustrate the effectiveness of the suggested approach.
