摘要：
A source separator is proposed based on a contrast functional recently introduced. This contrast is not squaring the sample cumulants, which allows a reduced variance on the estimated separating matrix. In fact, it is shown by extensive computer experiments how this contrast compares with JADE, and with the contrast squaring sample fourth-order cumulants. Then a procedure is outlined that allows to compute the asymptotic theoretical performances.
