An efficient beamforming technique based on the recently proposed quadrature mirror filter based multirate sub-band adaptive beamformer (QMF-MSAB), is presented. The improved technique uses only one adaptive processor for all sub-bands, resulting in a considerable reduction in hardware requirements. In addition, the new structure maintains the overall superiority of the multirate approach over full-band beamforming
