有限元Matlab程序，同时提供书籍的pdf文件，供同时学习使用(This book was written to be a undergraduate and introductory graduate level textbook, depending on whether the more advanced topics appearing in the end of each chapter are covered.)

说明：  用S变换对电压暂降进行检测，得到基频幅值，相位跳变，突变点，谐波检测，频率幅值包络线等特征量(The S-transform is used to detect the voltage sag, and the characteristic parameters such as fundamental frequency amplitude, phase jump, mutation point, harmonic detection, frequency amplitude envelope are obtained)

这是我在科研中编写的卡尔曼滤波程序，希望对大家有用，已调试好。(This is a Kalman filtering algorithm program. I have applied in filtering process by matlab.)

数字信号处理，离散时间系统的相位、结构与状态变量描述典型题，能更好的理解离散时间系统(Digital signal processing, discrete-time systems the phase, structure and state-variable description of a typical question, can a better understanding of discrete-time systems)

说明：  关于雨点的散射程序，希望和有关同行探讨探讨(The scattering process on the rain, hope, and the study of peer)

非均匀傅里叶变换是传统傅里叶变换的扩展,它尤其适合于适合于非均匀采样数据或要计算 任意频率的频谱.(Nonuniform Fourier Transform (NUFT) is the extension of traditional Fourier transform,it is particularly used for nonuniform-sampled data analysis and calculating arbitrary spectral.)

国外专家做的求解LMI鲁棒控制的工具箱,可以相对高效的解决LMI问题(foreign tool box of matlab,good method to solve problem of robust LMI)

音频得信号处理 画图 和数据得分析 根据声音画出音波图形(Paint the audio signal processing and data obtained was analyzed)

扩频通信系统仿真实验,　　　①传输的数据随机产生，要求采用频带传输（BPSK调制）； 　　　②扩频码要求采用周期为31的m序列； 　　　③仿真从基站发送数据到三个不同的用户，各不同用户分别进行数据接收； 　　　④设计三种不同的功率延迟分布，从基站到达三个不同的用户分别经过多径衰落（路径数分别为2，3，4）； ⑤三个用户接收端分别解出各自的数据并与发送前的数据进行差错比较。(Spread spectrum communication system simulation)
