摘要: The diagonal loading (DL) technique is the most widely used method to improve robustness of Capon beamformer in presence imprecise knowledge covariance matrix and desired signal's steering vector. selection DL level challenging practice might depend on some user-defined parameters which are possibly hard be determined. A fully automatic training-free for herein presented extract signal with constant modulus, a common feature communication signals. Simulated results beamforming performance have demonstrated efficacy proposed method.
