利用形态开—闭组合去除信号噪声，效果不错。可以参考。(Use form-closed combination remove a signal noise, the effect is good. Can reference.)

Gaussian_Window,Fourier_Transform的matlab代码例程(matlab code about Gaussian_Window,Fourier_Transform)

OFDM(Orthogonal Frequency Division Multiplexing)即正交频分复用技术，实际上OFDM是MCM Multi-CarrierModulation，多载波调制的一种。其主要思想是：将信道分成若干正交子信道，将高速数据信号转换成并行的低速子数据流，调制到在每个子信道上进行传输。正交信号可以通过在接收端采用相关技术来分开，这样可以减少子信道之间的相互干扰 ICI 。每个子信道上的信号带宽小于信道的相关带宽，因此每个子信道上的可以看成平坦性衰落，从而可以消除符号间干扰。而且由于每个子信道的带宽仅仅是原信道带宽的一小部分，信道均衡变得相对容易。本程序实现OFDM与QPSK技术的比较(This program realization technology and the OFDM QPSK technology)

说明：  很好的遗传算法,改改可以应用在很多方面.希望对大家有用(Good genetic algorithm, can be applied changed in many ways. Hope everyone useful)

数学建模中的一种评价算法--基于topsis熵权评价法和改进的灰色预测模型代码，里面的内容根据自己的情况改。(An evaluation algorithm in mathematical modeling is based on the TOPSIS entropy weight evaluation method and improved grey prediction model code, and the contents are changed according to their own situation.)

kde全称是kernel density estimation.基于核函数的概率密度估计方法。是模式识别中常用的算法之一(KDE which is kernel density estimation is used to estimate probabilty function. It is mostly used in pattern recogntion)

说明：  关于圆盘耦合摆的研究，将介绍单圆盘耦合发电机模型和双圆盘耦合发电机模型的非线性方程组。通过对方程组的分析和MATLAB模拟计算，指出前者电流有稳定的周期解，后者在两圆盘角速度不同时可能进入混沌态，并且通过数值计算其Lyapunov指数（其中一个，出现了正值）来证明其混沌态(Research on the disk coupled pendulums, will introduce the model of a single disc and double disc coupling generator generator model coupled nonlinear equations. Equations through the analysis and MATLAB simulation, that the former current of a stable periodic solution, which is not the same in the two-disc angular velocity may enter the chaotic state, and by numerical calculation of its Lyapunov index (one of which, there have been positive) to prove the chaotic state)
