Abstract
The present invention uses a method of processing signals in which signals received from an array of sensors are subject to system having a first adaptive filter arranged to enhance a target signal and a second adaptive filter arranged to suppress unwanted signals. The output of the second filter is converted into the frequency domain, and further digital processing is performed in that domain. The invention is further enhanced by incorporating a third adaptive filter in the system and a novel method for performing improved signal processing of audio signals that are suitable for speech communication.
