- W2378994876 abstract "Blind separation of sources consists of recovering a set of signals in which only instantaneous linear mixing are observed.This paper presents a novel blind separation method of nonstationary sources when noises are α stable processes,the observed data are preprocessed using an empirical threshold value.To make full use of nonstationarity and temporal correlation of sources,we exploit sliding windows to form multiple time delay correlation matrices of the weighted observed data,then use approximately joint diagonalization to estimate the mixing matrix and source signals.The method is limited to the case of characteristic exponent α tending to unity,and computer simulation is provided to illuminate the high performance of the proposed method." @default.
