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.

智能天线下行加权向量的设计

智能天线有可能大幅增加基站的范围，并提高信号的干扰加噪声比。本文研究了下行链路权向量的设计问题，给出了当权向量的方向已知时的最优功率分配。并给出了加权向量优化设计的四个准则。仿真结果表明，本文所研究的最优功率分配方法具有一定的改进作用。
