Real-Time DSP Implementation of an Acoustic-Echo-Canceller with a Delay-Sum Beamformer

Traditional telephony uses only a single receiver for speech acquisition. If the speaker is standing away from the telephone, the signal will be weak and there will be interference sources from room reverberation. In addition, there is acoustic echo coming from the loudspeaker, which further interferes with the signal of interest. This research investigated the combination of common solutions to these problems. Electronic beamforming steered an array of microphones within software to enhance the signal power. Echo cancellation removed the echo coming from the loudspeaker. In combination these processing techniques can greatly enhance user experience.
