Abstract :
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.
