Distributed Signal Processing Algorithms for Acoustic Sensor Networks (2015)
Abstract / truncated to 115 words
In recent years, there has been a proliferation of wireless devices for individual use to the point of being ubiquitous. Recent trends have been incorporating many of these devices (or nodes) together, which acquire signals and work in unison over wireless channels, in order to accomplish a predefined task. This type of cooperative sensing and communication between devices form the basis of a so-called wireless sensor network (WSN). Due to the ever increasing processing power of these nodes, WSNs are being assigned more complicated and computationally demanding tasks. Recent research has started to exploit this increased processing power in order for the WSNs to perform tasks pertaining to audio signal acquisition and processing forming so-called ... toggle 6 keywordswireless (acoustic) sensor networks – distributed estimation – node-specific signal estimation – wiener filtering – audio processing – binaural noise reduction
