摘要
自适应波束形成技术是智能天线领域的核心技术,其利用自适应波束形成算法,根据用户的空域信息来产生空间定向波束,将波束的主瓣对准期望用户的来波方向,旁瓣或零陷对准干扰信号的来波方向。文中介绍了一种基于DSP结合FPGA的波束形成器的实现形式,该系统能够实时地处理数据,并很好地完成预定指标。
The technology of adaptive beam forming is the key technology in smart antenna. Adaptive beam forming algorithms are used to produce directional beam based on the spatial information of users. The main beam aims at the coming direction of desired user and the side lobe or null points at the coming direction of interfering user. This paper introduces an adaptive beam former based on DSP and FPGA. This system can realize the real-time data processing and achieve the expected indices.
