Abstract

This paper focuses on the influence of beamforming on the interference distribution of wireless communications systems. Through comparing broadcast beamforming and adaptive beamforming, some significant conclusions have been drawn. First, for most users the gain of adaptive beamforming as opposed to broadcast beamforming is noticeable in terms of both the user signal strength and the SINR. Secondly, the fluctuation of the user signal and the SINR becomes more severe with adaptive beamforming. Thirdly, although most users experience decreased interference, the interference of users located in some special areas, such as the cell edge, pointing to adjacent cell and at supplementary angles of interfering users, owing to the strong side lobe, may increase with adaptive beamforming.
