Abstract

Blind source separation (BSS) techniques have been extensively investigated in the last years, due to their large number of applications. There are two main approaches employed for such techniques: in the time-domain and in the frequencydomain. In this paper, we propose the use of a non-uniform DFT transform as a strategy for improving the behavior of two frequency-domain BSS algorithms.
