the infomax algorithm is a popular method in blind source separation problem. in this article an extension of the infomax algorithm is proposed that is able to separate mixed signals with any sub- or super-gaussian distributions. this ability is the results of using two different nonlinear functions and new coefficients in the learning rule. in this paper we show how we can use the distribution...

Background: Municipal solid waste is a serious environmental issue in human societies. The source separation is a necessity for efficient municipal waste management (MSW). Objective: The aim of this study was to evaluate the source separation rate of MSW in several Iranian cities, as well as to identify the determinance of the participation level in source separation. Methods: In this study, ...

This paper deals with the problem of Blind Source Separation. Contrary to the vast majority of works, we do not assume the statistical independence betwwen sources and explicitly consider that they are dependent. We introduce three particular models of dependent sources and show that their cumulants have interesting properties. Based on these properties, we investigate the behaviour of classica...

In this paper, we investigate the importance of the high frequencies in the problem of convolutive blind source separation (BSS) of speech signals. In particular, we focus on frequency domain blind source separation (FD-BSS), and show that when separation is performed in the low frequency bins only, the recovered signals are similar in quality to those extracted when all frequencies are taken i...
