In order to achieve the diversity gain with antenna arrays for moderate angle spread, we propose a beamforming algorithm that utilizes multiple eigenvectors, and apply this beamforming technique to IS2000 1X systems equipped with antenna arrays under a time-varying multipath fading channel environment. In the proposed beamforming method, the channel vector has been estimated using two basis vectors. Since the proposed beamforming algorithm utilizes two-dimensional signal subspace, it provides better performance than the conventional beamforming algorithm, which uses one beamforming signal space.
