Griffiths jim beamforming

WebAbstract: Adaptive beamforming techniques can be applied to the problem of reducing interference in monaural hearing aids from sound sources that are spatially separated from a target source. We implemented a two-microphone Griffiths-Jim [1] beamformer in simulated reverberant environments (anechoic space, living room, and conference room) … Webadaptive beamforming, which has been suggested by Frost and, in particular, the generalized sidelobe canceler (GSC) version, which has been developed by Griffiths and Jim, are the most widely used beamforming techniques. These methods rely on the assumption that the received signals are simple delayed versions of the source signal.
