摘要: 研究了自适应天线系统结构与加权算法.提出利用自适应滤波器,克服因干扰信号与用户信号同向到达带来的阵列抑制能力下降方案.进一步分析讨论了利用数字信号处理方法在基带实现波束形成.

关键词: 数字信号处理, 自适应天线, 滤波, 阵列

Abstract: The principle structure and algorithms of adaptive arrays is studied and the project of adaptive filter is also provided to suppressthe degradation while the interference signal arrives at the same direction with user signal. Furthermore, it analyses and discusses the digital beam forming(DBF) in base band.

Key words: digital signal processing, adaptive antenna, array, filter
