能够把输入信号分解为多个IMF分量，并进行Hilbert变换，求得信号的时频分布谱图。(Be able to input signal is decomposed into several IMF components and carry out Hilbert transform, time-frequency distribution obtained spectrum.)

KNN分类方法，用于文本分类工作的研究。(KNN classification method, for text categorization of the research work)

窗函数法设计数字滤波器——海明窗 非原创 原文章名称：基于窗函数法的FIR数字滤波器的设计 作者：张志田 何其文 湖南工业职业技术学院 电气工程系 刊载于湖南科技学院学报 2007年9月 第28卷9期(Window function method to design digital filters- Hamming window of non-original name of the original article: window function based on the design of FIR digital filters: Zhang Zhitian He Qiwen Hunan Vocational College of Electrical Engineering of Hunan University of Science published in 2007 Volume 28 on September 9)

对基带数字通信的位同步过程进行了仿真，采用Gardner算法，没有用插值。符号用SRRC进行脉冲成形，环路滤波器没有用PI回路，是简单的alfa，1-alfa低通滤波，NCO调整也比较简单。(Baseband digital communications for the bit synchronization process of the simulation, using Gardner algorithm, did not use interpolation. Carried out with SRRC pulse shaping symbols, did not use PI loop filter circuit is a simple alfa ,1-alfa low-pass filter, NCO is also relatively simple to adjust.)

说明：  这些文章讲述了分步傅里叶方法，通过这些方法可以数值解非线性薛定谔方程，并且模拟光在光纤中传输随距离变化的状态，是学习光传输比较好的资料(The article was about a split-step Fourier method, numerical solution of these methods can be non-linear Schrodinger equation, and simulation of optical fiber transmission in the state of change with distance, is to learn good information on optical transmission)

传统的完整的雷达成像RD算法，其中具体到了距离向、方位向德细节处理(the RD algorithm of traditional radar imaging,many detail are described in it,so it is very usefull for someone who is the first time to learn radar imaging )

Matlab最优化计算中的无约束多维极值问题(Matlab Optimization of unconstrained multi-dimensional calculation of extremal problem)

模糊自整定PID控制器设计。 本资料含有详细的PID控制器算法M文件、Simulink模型搭建、模糊控制器设计以及相应的技术文档分析。相信对您一定很有帮助(Fuzzy self-tuning PID controller design. This information contains details of the PID controller algorithm M files, Simulink models to build, fuzzy controller design and analysis of relevant technical documentation. I believe you must be helpful)

是一个关于经济周期的matlab程序，数值模拟了一个异质性经济的波动模型，非常有用，可以在此基础上进行很多扩展(Is a matlab program on the economic cycle, numerical simulation of a heterogeneous model of economic fluctuations, very useful and a lot of this expansion on the basis of)
