Per_spectrum

Emperical mode decomposition

基于matlab的自相关序列产生.用到了分数阶高斯噪声和Hurst参数.(Based on the autocorrelation matlab generated sequence. Used a fractional Gaussian noise and Hurst parameter.)

快速区域生长算法，已测试相当不错，欢迎感兴趣的达人们下载测试(Fast region growing algorithm has been tested pretty well, welcome to download the test of interest up to the people)

病态系统求解方法比较：龙格库塔4固定步长、变步长、吉尔法(Pathological system solving methods: Runge-Kutta 4 fixed step size, variable step size, Gill Law)

For the use of image processing filtering using satellite images is very important that the code how to describe.

Other program to estimate heterogeneous firm model

matlab开发工具箱中的支持向量机，光纤陀螺输出误差的allan方差分析，雅克比迭代求解线性方程组课设。( matlab development toolbox support vector machine, allan FOG output error variance analysis, Jacobi iteration for solving linear equations class-based.)

NADAV LEVANON 与 ELI MOZESON 写的一本关于雷达信号分析非常专业并且经典的书。里面有很多的 matlab 相关资料。(Written by NADAV LEVANON ELI MOZESON a radar signal analysis is very professional and classic books.There are many Matlab codes inside.)

用于生成AM,FM,PM,DSB，SSB，FSK，BPSK,QPSK,OQPSK,PI/4QPSK等调信号的matlab生成程序。(Used to generate the AM, FM, PM, DSB, SSB, FSK, BPSK, QPSK, OQPSK, PI/4 such as QPSK signal generated by the matlab program.)

本程序是关于卫星上下变频的简单的实现算法，首先产生双边带调制信号，与收本振混频后，通过低通滤波器完成下变频。再与发本振混频，通过高通滤波器后完成上变频(This program is a simple algorithm on the satellite and down-conversion, the first double-sideband modulation signal generated, after the close of the oscillator mixer, low-pass filter complete the conversion. Again and send the local oscillator mixer, followed by the completion of the high-pass filter frequency)
