波束形成DOA估计中的ESPRIT算法matlab程序(ESPRIT)

We see that HTH matrix is almost diagonal as the off diagonal elements are nearly zero. So we are getting exact estimation in case of PRN INPUT due to diagonality of HTH matrix. As seen that the unknown inpulse response ( h ) and estimated impulse response ( hth ) are coming out to be exactly same. The estimation even gets better for large N .as we get the HTH matrix perfect diagonal. So we come to know that we can estimate the unknown parameters exactly when PRN input is used.

说明：  关于图像处理仿真软件环境下的源程序，毕设中自己用过的，希望对你有用(On image processing simulation software environment of the source, complete set used in their hope that useful to you)

在有限区域内分布的稀疏不均的、具有一定分布结构的海量数据集的高效、高精度聚 类问题是一个尚未完全圆满解决的难题。针对Affinity Propagation 聚类算法(AP)的不足之处， 提出了两个改进型的聚类算法(In a limited area of uneven distribution of sparse, has certain distribution structure of the mass datasets of high efficiency, high precision together Problem is a perfectly solved problem has not yet completely. For Affinity Propagation clustering algorithm (AP) of the deficiencies, Put forward the two improved version of the clustering algorithm)

迭代生成LDPC码矩阵，初始矩阵为三行三列各元素均为1的矩阵。根据其tranner图依次迭代产生新的矩阵。(structural properties: (1)Each line is composed of p points (2)There is one and only one line between any two points (3)Each point lies on b lines (4)Any pair of lines has at most one common point )

模糊控制课程作业，针对给定的系统（传递函数）搭建了Simulink平台，对比了模糊控制与PID控制的效果，可通过选取不同的模糊逻辑规则与参数调节仿真结果。(In the course assignment of fuzzy control, a Simulink platform is built for a given system (transfer function). The effects of fuzzy control and PID control are compared. The simulation results can be adjusted by choosing different fuzzy logic rules and parameters.)
