In this paper we consider the problem of source separation for the case that sources are (second-order) nonstationary, especially their variances are slowly time varying. The differential correlation is exploited in order to capture the time-varying statistics of signals. We show that nonstationary source separation can be achieved by differential… CONTINUE READING
