An efficient systolic array for MVDR beamforming

An efficient systolic array for computing the minimum variance distortionless response (MVDR) from an adaptive antennas array is described. The MVDR beamforming problem amounts to minimizing, in a least-squares sense, the combined output from an antenna array subject of K independent linear equality constraints each of which corresponds to a chosen ´look direction´. The array is fully pipelined and based on numerically stable algorithm that requires O(p/sup 2/+Kp) arithmetic operations per sample time, where p is the number of antenna elements.<>
