摘　　要：智能天线利用数字信号处理技术,产生自适应定向波束,使天线主波束对准用户信号到达方向,旁瓣或零陷对准干扰信号到达方向,达到抑制干扰,提高移动通信系统容量的目的。文章研究了自适应波束形成的基本原理及其FPGA实现过程。The main function of smart antenna is to utilize beamformer to form adaptive directional beam of users. It offers a more efficient way to reduce interference in mobile communications systems, through the main narrow beams directed towards clusters of users, while at the time steering nulls towards interfering users, any reduction of interference level translates into improvements of system capacity. This paper studies the basic theory of beamformer and the FPGA implementation processing of beanformer.
