Abstract: This paper proposes a novel scheme to solve permutation ambiguity in frequency-domain for the separation of the convolutive mixing signals.

Towards this problem, we propose a method which uses reference signals. For each frequency bin, the permutation alignment is fixed by calculating correlation ...

In this paper, we present a new method for solving the permutation problem using microphone sub-arrays. It is based on the combination of two approaches ...

This paper presents a robust and precise method for solving the permutation problem of frequency-domain blind source separation. It is based on two previous ...

Oct 22, 2024 · We propose a new algorithm for solving the Blind Signal Separation (BSS) problem for convolutive mixing completely in the time domain. The ...

We need to align the permutation in each frequency bin so that a separated signal in the time domain contains frequency components from the same source signal.
