Method for generating noise references for generalized sidelobe canceling

摘要

This invention describes a method for generating noise references for adaptive interference cancellation filters for applications in generalized sidelobe canceling systems. More specifically the present invention relates to a multi-microphone beamforming system similar to a generalized sidelobe canceller (GSC) structure, but the difference with the GSC is that the present invention creates noise references to the adaptive interference canceller (AIC) filters using steerable beams that block out the desired signal when the beam is steered away from the desired signal source location.
