| 摘 要： | 基于来渡方向估计和自适应波束成形的智能天线系统,用多重信号分类(MUSIC)算法实现来波方向估计,辨识天线阵列上接收信号的各个方向,使用最小均方误差(LUS)的自适应算法控制天线的主辩方向,实现对期望信号的跟踪,同时实现对干扰信号的零陷处理.文中使用Matlab编程进行计算机仿真,通过仿真结果,MUSIC算法可以识别天线接收端的信号的入射方向,LMS算法可以实现对干扰信号的抑制.

| Abstract: | A smart antenna system based on estimated direction of arrival(DOA)and adaptive beamforming achieves DOA and identifies the directions of the received signals around the array antenna by the MUSIC algorithm,controls the direction of the main beam by the LMS algorithm and thus tracks the desired source signal,and at the same time generates deep nulls in the direction of interfering signals.Matlab simulation results show that the MUSIC algorithm can identify the direction of the signal received at the antenna... |
