Abstract :
Smart antennas have the potential to substantially increase the range of base stations and boost the signal to interference plus noise ratios of signals. In this paper we study the problem of downlink weighting vector design, and give the optimal power assignment when the orientations of the weighting vectors are known. Also four criteria for the optimal weighting vector design are given. Simulation results have shown the improvement offered by the optimal power assignment method studied here.
