Rate-Distributed Spatial Filtering Based Noise Reduction in Wireless Acoustic Sensor Networks
Jie Zhang, Richard Heusdens, Richard C. Hendriks
In wireless acoustic sensor networks (WASNs), sensors typically have a limited energy budget as they are often battery driven. Energy efficiency is therefore essential to the desig…
A Low-Cost Robust Distributed Linearly Constrained Beamformer for Wireless Acoustic Sensor Networks with Arbitrary Topology
Andreas I. Koutrouvelis, Thomas W. Sherson, Richard Heusdens +1
We propose a new robust distributed linearly constrained beamformer which utilizes a set of linear equality constraints to reduce the cross power spectral density matrix to a block…
An evaluation of intrusive instrumental intelligibility metrics
Steven Van Kuyk, W. Bastiaan Kleijn, Richard C. Hendriks
Instrumental intelligibility metrics are commonly used as an alternative to listening tests. This paper evaluates 12 monaural intrusive intelligibility metrics: SII, HEGP, CSII, HA…
An instrumental intelligibility metric based on information theory
Steven Van Kuyk, W. Bastiaan Kleijn, Richard C. Hendriks
We propose a monaural intrusive instrumental intelligibility metric called speech intelligibility in bits (SIIB). SIIB is an estimate of the amount of information shared between a…
Microphone Subset Selection for MVDR Beamformer Based Noise Reduction
Jie Zhang, Sundeep Prabhakar Chepuri, Richard C. Hendriks +1
In large-scale wireless acoustic sensor networks (WASNs), many of the sensors will only have a marginal contribution to a certain estimation task. Involving all sensors increases t…
