WebThe time delay beamformer compensates for the arrival time differences across the array for a signal coming from a specific direction. The time aligned multichannel signals are coherently averaged to improve the signal-to-noise ratio (SNR). Now, define a steering angle corresponding to the incident direction of the first speech signal and ... http://www.labbookpages.co.uk/audio/beamforming/delaySum.html
