Rate-Constrained Noise Reduction in Wireless Acoustic Sensor Networks
IEEE/ACM Transactions on Audio, Speech, and Language Processing, 2020 Wireless acoustic sensor networks (WASNs) can be used for centralized multi-microphone noise reduction, where the processing is done in a fusion center (FC). To perform the noise reduction, the data needs to be transmitted to the FC. Considering the limited battery life of the devices in a WASN, the total data rate at which the FC can communicate with ...
