Abstract

Adaptive antenna arrays have been widely studied to reduce multiuser interference by spatial suppression. The lattice algorithm, based on least square estimation, is investigated to realize adaptive antenna beamforming. Both analytical and simulation results show that this algorithm not only has fast convergence, but also good multiuser interference suppression performance. Furthermore, the antenna weights iteration processes are discussed in different multiuser interference conditions
