Improved Frequency Domain Blind Source Separation for Audio Signals via Direction of Arrival Knowledge
نویسندگان
چکیده
The sound pollution is a common and serious problem in modern cities. Examples of sources of sound pollution are other speakers, traffic and household devices such as vacuum cleaner, air conditioner, TV and radios. These sound interference sources degrade the performance of audio devices such as hearing aids, smart TVs and forensic recorders. One way to tackle this problem is via Blind Source Separation (BSS) algorithms using microphone arrays. In this paper, we propose a technique to improve the performance of frequency domain BSS (FDBSS) by taking into account the direction of arrival (DOA) knowledge. With our proposed scheme, a significant improvement is obtained for end fire angles.

Modulation domain blind source separation for noisy speech mixture
In this paper, we propose a noise-robust blind speech separation (BSS) method by using two microphones. We first use modulation domain real and imaginary spectral subtraction (MRISS) to enhance both magnitude and phase spectra of the speech mixture inputs. We then estimate the direction of arrivals (DOAs) of the speech sources and perform time-acoustic-modulation frequency masking to recover th...
متن کاملA robust approach to the permutation problem of frequency-domain blind source separation
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 approaches: the direction of arrival estimation approach and the inter-frequency correlation approach. We discuss the advantages and disadvantages of the two approaches, and integrate them to exploit the both advantages. We also present a c...
متن کاملReal-time Blind Source Separation and Doa Estimation Using Small 3-d Microphone Array
We present a prototype system for real-time blind source separation (BSS) and directions of arrival (DOA) estimation. Our system uses a small three-dimensional array with 8 microphones and has the ability to separate signals distributed in threedimensional space. The mixed signals observed by the microphone array are processed by Independent Component Analysis (ICA) in the frequency domain. The...
متن کاملArray Geometry Arrangement for Frequency Domain Blind Source Separation
In this paper, we propose a method for solving the permutation problem of frequency domain blind source separation (BSS) when the number of source signals is large, and the potential source locations are omnidirectional. Geometric information such as direction of arrival is helpful for solving the permutation problem, but the information becomes more uncertain as the number of source signals in...
متن کاملGeometrically constrained permutation-free source separation in an undercomplete speech unmixing scenario
Frequency domain blind source separation (BSS) problems are typically solved in each frequency bin independently and therefore require additional measures to resolve the resulting permutation problem. In this paper, a frequency domain methodology is presented based on a recently introduced extension of Independent Component Analysis (ICA) to multi-variate components which uses a multi-variate a...
