A novel systolic array processor for MVDR beamforming

A fully pipelined systolic array for computing the minimum variance distortionless response (MVDR) was first proposed by J.G. McWhirter and T.J. Shepherd (1989). The fundamental concept is to fit the MVDR beamforming to the nonconstrained recursive least-squares (RLS) minimization. A different approach is proposed for MVDR beamforming which does not require the nonconstrained RLS minimization; then a fully parallel and pipelined systolic array is presented for the newly proposed algorithm, and finally the similarity and differences between both MVDR beamforming designs are described
