本人编写的ofdm系统中的em信道估计matlab仿真程序，可直接运行(I ofdm prepared by the system of channel estimation em Matlab simulation program can be run directly)

龙格库塔法的编程,龙格库塔法的编程龙格库塔法的编程(Runge-Kutta method of programming)

小波和希尔伯特两种算法对同一个信号进行处理后的比较，(It is about the wt and hilbert transform for the same signal)

说明：  在地球科学中，误差分析非常实用，这里提供测地学常用的误差分析代码(Error Ellipses in Geodesy)

对信号进行傅里叶变换的程序，附带实验报告，有兴趣的同学可以下载(Fourier transform of the signal process, with lab reports, students who are interested can download)

本章首先介绍了TEQC软件的基本功能，包括格式转换、数据编辑、质量检查、单点定位。接着列出了一些TEQC软件的常用命令，并作了详细的注释(This chapter introduces the basic functions of TEQC software, including format conversion, data editing, quality control, single point positioning. Then a list of some common commands TEQC software, and made detailed notes)

说明：  跳频是按跳频序列随机改变一个信道所占有频道频率的技术。在GSM 系统中，可利用跳频技术频率分极和干扰分极的特点，改善网络质量。引入跳频技术，可保证在网络软拥塞不上升的情况下，频率复用度较小。(FH frequency hopping sequence is based on a random channel change in the country channel frequency technology. In the GSM system, can make use of frequency hopping technology sub-polar and polar characteristics of interference and improve network quality. The introduction of frequency-hopping technology to ensure that congestion in the network does not increase in the soft case, a smaller frequency reuse moment.)

谱元法（sem)谱结构程序，用于各类波场的模拟计算(Spectral element method (sem) spectral structure of procedures for the various types of wave field simulation)

关于电力系统潮流计算方面的小程序，对电力系统的从业人员及学生很有用！(on the power flow calculation of the small procedures, the power system employees and students useful!)
