Abstract

The intelligent beamforming algorithm that transmits minimum power to the nodes in out-of main beam regions to prevent unwanted traffic in CSMA/CA (carrier sensing multiple access /colision avoidance) systems is presented, while main beams focus on specific nodes. To design the intelligent complementary beamforming, Gram-Schmidt orthogonalization is utilized, whose beam pattern exhibits perfect nulling performance at the main beam angles, and provides uniform power out of main beams. The proposed method can be utilized with any arbitrary beamforming algorithms and can control the power with a small value of ε to satisfy detection criteria of communication standards.
