dfa 时间序列的赫斯特指数的计算线性趋势的拟合

vmd经验模态分解，修正的vmd,有实际例子。(Vmd empirical mode decomposition, the revised vmd, there are practical examples.)

在现代谱估计中，用自相关的无偏估计代替周期图中自相关函数的有偏估计，可能导致出现负的谱估计值，因此采用BT谱估计器的方法(In the modern spectral estimation, the use of self-related unbiased estimate the figure to replace the cycle of auto-correlation function biased estimate may lead to a negative estimated value of the spectrum, so the use of BT s method of spectral estimation)

说明：  国外关于雷达线性和非线性调频技术的描述包含脉冲压缩结果图(Abroad on the radar, linear and nonlinear FM pulse compression technology, includes a description of the results of Figure)

说明：  这里面所有源码均为《通信原理——基于Matlab的计算机仿真》（郭文彬 桑林.北京邮电大学出版社）上的，自己录入整理，均可以运行，方便查找(Communication Principle Simulation)

用最速下降法求解多维函数的极值 function [x,minf]=minFD(f,x0,var,eps) 目标函数：f 初始点：x0 自变量向量：var 精度：eps 目标函数取最小值时的自变量值：x 目标函数的最小值：minf( With the steepest descent method for solving the multi-dimensional function of the extreme value function [x, minf] = minFD (f, x0, var, eps) target function: f Initial Point: x0 argument vector: var Accuracy: eps target function takes the minimum value of the independent variable values: x minimum target function: minf)

机器学习算法， 使用Fisher score进行特征选择。(Machine learning algorithms, feature selection using Fisher score.)

本文件是有关于QPSK仿真的matlab源码。(This document is QPSK simulation on matlab source.)
