3D-beamforming codebook design based on directly search for millimeter-wave communications

Abstract

To solve symmetry and beam distortion problem in 3D-beamforming codebook design by direct product method, this paper proposes a codebook design scheme, which is generated by search in two-dimensional matrix. The method can generate asymmetric beam and solves the problem of beam distortion in the direction of large angle. It has more flexibility and can meet the demand for more scenes.
