摘　　要：为了使智能天线获得最大的处理增益,基于传统的on-off波束赋形算法,提出了一种新型的波束赋形算法。该算法通过利用最速下降法最大化用户数据的SINR,获得入射平面波到达各阵元相对到达参考阵元距离差的最优解,从而极大化目标函数,在此基础上,求取智能天线阵元的最优波束赋形权值。仿真表明,采用论文提出的算法可以大大改善智能天线系统性能。In order to get the maximum processing gain, this paper presents a novel beamfonning method based on the on - off beamforming method. The optimum solution of the relative distance , that the wave impinges on the reference elements, can be obtained through the maximization of SINR, so it can maximize the objective function. Based on this, the optimum beam weight of smart antenna array element can be obtained. Simulation results have shown that great improvement on smart antenna system can be achieved.
