cyclostationarity-tool

matlab程序设计与应用，主要是简单的偏微分方程及画图讲解(matlab program design and application, mainly simple partial differential equations and drawing on)

本程序是Matlab的Simulink模块程序。模拟虚拟输出队列。是通信建模的入门模块。欢迎大家学习交流(This program is Matlab' s Simulink module program. Analog virtual output queues. Getting Started modules in communications modeling. Welcome to the Learning Exchange)

说明：  用matlab做成的维纳滤波器程序，跟踪先验信噪比使用直接判决的方法进行滤波(Made use of the Wiener filter matlab program to track a priori signal to noise ratio using a direct method of filtering decision)

薛定宇的两个MATLAB程序的源代码，希望对大家有用。(Xue Dingyu two MATLAB source code, we hope to be useful.)

产生一个长为1000的二进制随机序列，“0”的概率为0.8，”1”的概率为0.2； 对上述数据进行归零AMI编码，脉冲宽度为符号宽度的50 ，波形采样率为符号率的8倍，画出前20个符号对应的波形（同时给出前20位信源序列） 改用HDB3码，画出前20个符号对应的波形 改用密勒码，画出前20个符号对应的波形 分别对上述1000个符号的波形进行功率谱估计，画出功率谱 改变信源“0”的概率，观察AMI码的功率谱变化情况(A length of 1000 random binary sequence, and " 0" with a probability of 0.8, " 1" with a probability of 0.2 the AMI code above zero, the pulse width of the symbol width of 50 , the waveform sampling rate Symbol rate 8 times, draw the top 20 of the waveform corresponding to the symbol (the first 20 and gives the source sequence) switch HDB3 code, the first 20 to draw a waveform corresponding to the symbol to switch Miller code, the first 20 symbols correspond to draw The waveforms of the symbol of the waveform 1000 power spectrum estimation, shown to change the source power spectrum " 0" , the probability of observation of the power spectrum of AMI code changes)

说明：  混沌工具函数 function [x,y]=henon(n,level,a,b,x0,y0)(chaos function function [x,y]=henon(n,level,a,b,x0,y0))

有源滤波器，滤波器的分类，滤波器的用途，滤波器的指标(Active filter, the filter classification, the use of filters, filter indicator)

一种基于加权隐马尔可夫的自回归状态预测模型(Based on weighted HMM state autoregression prediction model)

说明：  计算概率潮流，所用算例为IEEE-33节点配电网系统。(Probabilistic load flow calculation.The example is IEEE-33 node distribution network system.)
