Wiener Multichannel Filtering in the Frequency Domain,

Abstract

This report presents the theory behind the frequency-domain approach to optimum beamforming as implemented with Wiener multichannel filters, along with algorithms for actually designing the filters. There are other approaches to optimum beamforming that could be taken with comparable success. However, Wiener's approach is the optimum under the least-mean-square criterion for signal extraction. For this reason, Texas Instruments has chosen to use Wiener's approach for initial evaluation of optimum beam-forming before considering other approaches that approximate optimum.
