Blind Separation of Convolutive Mixtures using Nonstationarity and Fractional Lower Order Statistics (FLOS) Application to Audio Signals

In this paper, we introduce new time-varying fractional spectral matrices to exploit both the nonstationarity and heavy-tailed sources properties for blind separation of convolutive audio mixtures. We define these spectrum matrices, that are different for various delays, using fractional lower order...
