Abstract

In this paper, we present a new multiuser beamforming transmission scheme for multiuser multiple-input multiple-output (MIMO) systems. The new scheme is built upon the conventional single-user random beamforming system and to design the additional beamforming vectors in order to minimize the interuser interference. We analytically quantify the sum-rate performance of the resulting incremental beamforming scheme. We showed through selected numerical examples that the proposed scheme can offer considerable sum-rate performance gain with limited additional system complexity.
