Wideband adaptive LMS beamforming using QMF subband decomposition for sonar
This paper describes the utilization of wideband LMS adaptive beamforming with QMF filterbanks decomposition for sonar application. The obtained results showed that applying the new algorithm yields better results than the time domain LMS beamformer (TD). The subband LMS beamformer isolates the interference in its own band and uses that band beamformer to steer a null in its direction, this capability enables the other beamformers to adapt independently without been affected by the interference.
