给出了kf ekf ukf upf的matlab源程序，通过用户自己修改可以方便的实现各种系统辨识。(Given kf ekf ukf upf the matlab source code through the user' s own can be easily modified to achieve a variety of system identification.)

说明：  利用costas环实现载波同步的matlab程序，载频10mHz(Costas loop to achieve carrier synchronization using the matlab program, carrier frequency 10mHz)

绘制自旋航天器的相平面图形，改变参数可以绘制不同情况下的姿态(Draw spacecraft spin phase planar graph, changing the parameters can be plotted attitude under different circumstances)

说明：  惯性导航系统工具箱 能有效帮助仿真惯性导航系统(Inertial navigation system simulation toolbox can be effective in helping inertial navigation system)

基于牛顿拉夫逊的潮流计算，这个简单可以直接查看结果，9节点(Can directly view the results based on the Newton Raphson power flow calculation, this simple)

主要内容(signal_analyzer.rar)如下： test1.txt 第一列为时间t，0.001s为步长；第二列为系统的输入信号；第三列为系统的输出信号。 signal_analyzer.m首先将test1.txt 的数据读入workspace，然后进行FFT，分析出两信号的频率，输出对于输入的幅值衰减（db），输出对输入的相位差。 (Main Content (signal_analyzer.rar) as follows: test1.txt the first time as t, 0.001s for the step the second as the input signal the third as the system output signal. signal_analyzer.m first test1.txt the data read into the workspace, and then FFT, the frequency of the two signals, the output amplitude for input attenuation (db), the output of the input phase difference.)

matlab算法分子中第七章的内容,其他内容陆续上载中请稍后(matlab algorithm in Chapter VII of the molecular content, and other content be uploaded later requested)

电网三相短路电流仿真，可以自己设定哪个短路(Grid three-phase short-circuit current simulation can be set for which short-circuit)

这是东南大学信息科学与工程学院《数字信号处理 第二版》第五章的实验，关于FIR滤波器的 每个题去掉注释号“ ”后分别运行( This is the School of Information Science and Engineering, " Digital Signal Processing Second Edition" Southeast University Chapter of experiments run on respectively after each question FIR filter uncommented number " " )

实现KALMAN滤波器设计,对刚刚开始现代数字信号处理的同胞们有借鉴作用(Kalman filter design to achieve the just the beginning of modern digital signal processing compatriots have reference)
