Delta-Modulation-(DM)

matlab based on power electronics and development hj

Weighted covariance function. Allows to give more weight on recent observations.

内含高等数值分析中lanczos过程.minre算法，cg法的matlab程序(Contains advanced numerical analysis lanczos process. Minre algorithm, cg method matlab program)

OFDM技术做为4G的关键传输技术，得到了广泛重视。本matlab文件为适合于OFDM系统的动态子载波分配算法。目的是提高频谱使用效率。(dynamic sub-carrier allocation(matlab))

gpr transmitter , and receiver , for ground penetrating radar

This program is for interpolating the trapozoidal method for mathematical calculations done in matlab.

在DOA估计中，实际测量和理论肯定存在误差，比如通道误差，阵元位置误差，我们提出一种toplitz的预校正方法。(In the DOA estimate, the actual measurement and theory certainly exist errors, such as channel error, array (position errors, we put forward a kind of toplitz or calibration methods. )

实现克里金插值，通过实现matlab实现该方法，可以滤波，并得到比较好的DEM。(Kriging interpolation to achieve, through the realization of Kriging can be filtered, and get better DEM.)

This function used to calculate PCA of image.

说明：  关于预测控制的MATLAB-s-function模块编写。 网络化控制系统是一种通过网络实现传感器，控制器和执行器之间数据交换的分布式实时反馈控制系统。其应用领域广泛，包括过程工业，航天工程，运输管理，机器控制，远程手术，智能家居等。具有长距离数据交换与共享，成本低, 便于安装和维护，高灵活性和可靠性，易于重配置及高移动性等优势。同时，由网络化控制系统引起的网络诱导时延和其共享、开放、可进入等特点对系统稳定性和安全性造成的影响也不可忽略。故本文设计了一种网络化预测输出跟踪控制系统以解决网络时延问题，并站在安全的角度研究虚假数据注入攻击问题(MATLAB-s-function.Networked control system is a distributed real-time feedback control system that realizes data exchange among sensors, controllers and actuators through network. Its applications range is wide, including process industries, aerospace engineering, transportation management, machine control, remote surgery and smart homes.)
