Blind Synchronization in Wireless Acoustic Sensor Networks
IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2017The challenge of blindly resynchronizing the data acquisition processes in a wireless acoustic sensor network (WASN) is addressed in this paper. The sampling rate offset (SRO) is precisely modeled as a time scaling. The applicability of a wideband correlation processor for estimating the SRO, even in a reverberant and multiple source environment, is ...

Network-Aware Optimal Microphone Channel Selection in Wireless Acoustic Sensor Networks
IEEE International Conference on Acoustics, Speech, and Signal Processing, 2021To address the vital problem of selecting the most useful microphones in wireless acoustic sensor networks, this paper proposes a novel, general-purpose approach that accounts for both acoustic and network aspects and remains application-agnostic for ...

Energy-Efficient Sparsity-Driven Speech Enhancement in Wireless Acoustic Sensor Networks
IEEE/ACM Transactions on Audio Speech and Language Processing, 2023Wireless acoustic sensor network (WASN) has shown a superiority over conventional microphone arrays in many aspects. There exists an important tradeoff between the performance and power consumption, as usually the sensors are power driven with a limited ...
