Intelligent Method For Designing Exact Orthogonal Blocking Matrix into Robust Wideband Beamformer Using Auxiliary Sensors

摘要

An innovative method for wideband adaptive beamforming is presented. This method can allow large desired-direction error by generating a wide and deep null around the desired-direction at the blocking matrix output. Moreover, it can provide good suppression performance for both directional and omni-directional interference and noise signals. Simulation results are included to illustrate the effectiveness of the proposed method.
