title: A fractional filter-based beamformer architecture using postfiltering approach to minimize hardware complexity.
abstract: A novel beamformer architecture using fractional delay filters is proposed and verified through experiments. By performing interchannel summation prior to filtering operation in the manner producing no error, the proposed architecture requires only three four-tap filters for the whole beamformer and four simple demultiplexers per each channel.
