Distributed noise cancellation method and device based on utility fusion, equipment and storage medium

Abstract

This application discloses a distributed noise cancellation method, apparatus, device, and storage medium based on utility fusion, relating to the field of noise cancellation technology. The distributed noise cancellation method based on utility fusion includes: acquiring frequency domain signals of nodes in a wireless microphone network, acquiring compression vectors and relative utility values; compressing the frequency domain signals according to the compression vectors to obtain compressed data of the nodes, and acquiring compressed data of neighboring nodes corresponding to each node based on the compressed data; performing weighted fusion of the neighboring node compressed data according to the relative utility values ​​to obtain fused data of each node, and obtaining local data of each node based on the fused data and the frequency domain signals; performing voice activity detection on the frequency domain signals to obtain detection results; and performing noise cancellation on the local data based on the detection results to obtain a time-domain output signal. This application can improve the noise cancellation effect of wireless microphone networks.
