画出下述情况下均匀线阵方向图 1）计算来波方向为0度方向图 2）画出来波方向为45度时的方向图 3）画出来波方向为0度，幅度取分贝数：20log***（单位为dB）时的方向图 4）画出来波方向为0度，随着阵元数的增加，当N=16，N=32时的方向图，并对方向图的变化情况进行说明-Draw the following conditions uniform linear array 1) calculation of wave direction is 0 degrees

程序产生N个随机的整数，存放在数组a中。然后根据数组a建立线性链表， 再删除链表中所有重复元素，并输出无重复元素结点的链表结点的值 -Program generates a random integer N, stored in the array a. Then establish a linear list of the array,     Then delete all duplicate elements in the list, and output

一篇非常实用的无线通信方向的文献，是关于cdma系统中doa估计的经典-The use of antenna arrays in wireless communications makes it possible to estimate the directions of arrival (DOAs) of impinging waveforms. The latter can be exploited to enhance channel estimation accuracy o

In this paper, a fast search-free method for direction-of-arrival (DOA) estimation with coprime arrays was proposed. It is based on the use of methods that operate on the uniform linear subarrays of the coprime array and that enjoy many proces
