中文说明：智能天线基于数字信号处理算法。智能天线系统成为能够定位和跟踪的信号两个： 用户和波束和动态适应天线方向图来提高在招待会感兴趣的信号方向与最小化干扰信号不感兴趣的方向。智能天线系统的性能大大取决于数字信号处理效率算法在自适应天线阵的智能天线，找到所需的信号，各种方向的到来使用 （DOA） 估计算法。DOA算法估计事故飞机的数目波浪对阵列天线和他们的角度发病率。本文介绍的性能DOA 算法音乐上均匀线性数组。仿真结果表明，在音乐中该决议的 DOA 技术算法随着数量的快照，阵列数目元素和信号噪声比的增加。
English Description：
Smart antennas is based on digital signalprocessing algorithms. The smart antennas systembecomes capable to locate and track signals by theboth: users and interferers and dynamically adaptsthe antenna pattern to enhance the reception inSignal-Of-Interest direction and minimizinginterference in Signal-Of-Not-Interest direction.Performance of smart antenna system greatlydepends on efficiency of digital signal processingalgorithms In adaptive array smart antenna, tolocate the desired signal, various direction of arrival(DOA) estimation algorithms are used. The DOAalgorithms estimate the number of incidents planewaves on the antenna array and their angle ofincidence. This paper investigates performance ofthe DOA algorithm MUSIC on the uniform lineararray . The simulation results show that in MUSICalgorithm the resolution of the DOA techniquesimproves as number of snapshots, number of
