摘要:
A method for temporal adjustment of adaptation control of an adaptive interference canceller (AIC) 21 based on spatially weighted beamforming pre-processing. Spatial blocking performance is enhanced while generating noise references for the AIC 21-N by a beamformer, by introducing dynamic adjustment to the AIC filter adaptation control (46).
