Frequency-Domain Blind Source Separation employing a Non-Uniform DFT

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.
