摘要：Blind signal processing (BSS) is a fairly new and generally applicable technique. A very intuitive and important principle for the BSS problem is to maximize/minimize non-Gaussianity. Gaussian moments are introduced here as a quantitative measure of non-Gaussianity for a random variable. A proper contrast function is presented correspondingly that has not asymptotic bias even in the noisy context. After maximization of the contrast function, an improved BSS algorithm is introduced correspondingly. Computer simulations demonstrate the efficiency of the proposed approach. © Springer Nature Switzerland AG 2019.
