Geometrically Constrained Decentralized Independent Vector Analysis for Distributed Microphone Arrays
Changda Chen, Yichen Yang, Wei Liu +4
This paper proposes a geometrically constrained decentralized independent vector analysis (GC-Dec-IVA) method for distributed microphone arrays. Recently proposed Dec-IVA method en…
Neural Network-Based Time-Frequency-Bin-Wise Linear Combination of Beamformers for Underdetermined Target Source Extraction
Changda Chen, Yichen Yang, Wei Liu +1
Extracting a target source from underdetermined mixtures is challenging for beamforming approaches. Recently proposed time-frequency-bin-wise switching (TFS) and linear combination…
Robust Online Overdetermined Independent Vector Analysis Based on Bilinear Decomposition
Kang Chen, Xianrui Wang, Yichen Yang +6
Online blind source separation is essential for both speech communication and human-machine interaction. Among existing approaches, overdetermined independent vector analysis (Over…
Accelerated Convolutive Transfer Function-Based Multichannel NMF Using Iterative Source Steering
Xuemai Xie, Xianrui Wang, Liyuan Zhang +2
Among numerous blind source separation (BSS) methods, convolutive transfer function-based multichannel non-negative matrix factorization (CTF-MNMF) has demonstrated strong performa…
Low algorithmic delay implementation of convolutional beamformer for online joint source separation and dereverberation
Kaien Mo, Xianrui Wang, Yichen Yang +2
Blind-audio-source-separation (BASS) techniques, particularly those with low latency, play an important role in a wide range of real-time systems, e.g., hearing aids, in-car hand-f…
