| Abstract: | In this paper, a QR-RLS based Minimum Variance Distortionless Responses (MVDR) method, and its systolic array processor, are proposed. The QR-RLS based MVDR has many advantages, such as numerical stability, computational efficiency and pipelined structure in implementation. We also point out that the conventional method, MVDR using QR-RLS method by directly forcing the desired signal to zero is not correct. Numerical experiments are carried out to illustrate the ffectiveness of the proposed method. | ||
