Abstract

We consider a beamforming scheme for binaural hearing aids and analyze the effects of quantization on its performance. A limited bandwidth wireless link is assumed between the binaural hearing aids for communication from one ear to the other ear, where signals are then processed using a generalized sidelobe canceller (GSC). We consider the case where observations are quantized before transmission, and study the performance of the GSC beamformer under quantization errors.
