提取信号包络的小程序，是用matlab编写的。(Extraction of small signal envelope process, It is a matlab file.)

orthogonal projection algorithm

一本MATLAB学习的好资料，适合从零基础的学习者。(This is a book of introduction of Matlab for beginners.)

说明：  这是一个可以手动点击图片上任意一个点的时候，可以查看该点的亚像素坐标，精确到0.0001(This is a can manually click on the picture when any one point, you can see the point of the sub-pixel coordinates, accurate to 0.0001)

This Program draw spectral correlation function of mixed two signal based on QPSK and QAM

信噪比，计算公式是信号能量比上噪声能量，有助于分析信号成分的(Signal-to-noise ratio, and the calculation is signal energy on energy than noise, help analysis of signal components )

实现基于加权最小二乘法的电力系统状态估计算法，以于老师写的书里面四节点算例仿真(Implementation based on weighted least-square method of power system state estimation algorithm, with the teacher wrote the book four node example simulation)

通过AR模型模拟得到风荷载，其模拟是有davenport风速谱得到的(Wind load is obtained by AR model simulation, which is based on Davenport wind speed spectrum.)

可以通过计算机向下位机发送串口数据,适合初学者，用matlab实现(send data from pc)
