Solving Permutation Problem in Blind Source Separation of Speech Signals: A Method Applicable for Collinear Sources

Abstract

Blind source separation (BSS) in frequency-domain involves a permutation problem: the permutation ambiguity of ICA in each DFT bin should be aligned so that a separated signal in the time-domain contains frequency components of the same source signal. This paper presents a method for solving the permutation problem, which does not require any information… (More)
