Abstract
In this paper we proposed a new approach that clusters mobile users before downlink beamforming and broadens beams and nulls within the beamforming calculation. We first investigate the broadening beamforming scheme to alleviate inaccuracies in DOA estimation. Next we exam how to group the mobile users, with the constraint of separation angle, to enhance downlink beamforming. Simulations show that the downlink beamforming complexity is decreased dramatically with limited performance loss.
