Abstract :
In a smart antenna system, downlink weighting vectors should be so designed that each user can receive the desired signal with high SINR while not too much interference is generated to other signals. In this paper, we study the optimal power assignment given the orientations of the weighting vectors. Also four criteria for the optimal weighting vector design are given. Simulation results show significant improvements using the proposed technique
