Blind Separation of Two Signals by Estimation of Two Fourth-Order Cumulants

The problem is to recover stochastic signals from an unknown stationary linear mixture. The paper presents analytical solution for blind separation of two statistically independent signals. It equires two fourth-order input sample cumulants to be estimated, contrary to the solution given in references that requires estimation of three fourth-order input sample cross-cumulants. When real-time separation problem is considered this difference can be significant.
