MRAS方法无速度传感器控制异步电机模型，可以闭环，可直接用于dSpace实时控制。(MRAS methode for sensorless control of induction machine)

ID3算法的matlab实现，包含了分类中的所有子函数代码。(ID3 algorithm matlab implementation, including the classification of all the subfunctions code.)

该程序基于C++、MFC、GDI+。使用ADO数据库访问技术。实现的主要功能包括备忘录、计划、节日、朋友生日的提醒等，同时拥有强大的查找功能。支持换肤和快捷的音乐播放。允许用户自制皮肤。eLife!的换肤功能全部由GDI+实现。(The program is based on c++, MFC, GDI+. Using ADO database access technology. Implementation of main functions include memos, plans and holiday, friends birthday reminder, have powerful search function at the same time. Supports avi and fast music playing. Allows the user to homemade skin. ELife! All by GDI+ realize change skin function. )

直接序列扩频通信中采用QPSK调制时，须将产生的串行数据首先串并变换成两路，本程序就是实现这种串并变换！(Direct sequence spread spectrum communications using QPSK modulation, it is necessary to have a string of serial data and converted into the first two, the process is to realize such a string, and transform!)

WinpCap开发包例子：1. devicelist.c 获得本机网络设备的列表 2. cappacket.c 抓取网络中的数据包 3. sendpacket.c 发送自己填充的一个数据包 4. statics.c 对网络中的数据进行统计 5. filter.c 按指定规则对捕获的数据包进行过滤-WinpCap development kits examples : 1. devicelist.c access the computer network equipment list 2. cappacket.c crawls Network data packet 3. sendpacket.c send their fill of a data packet 4. stati cs.c right network data statistics 5. filter.c designated by the rules of the capture of data packets conducted Filter

控制其他程序成为自己的子窗体,属vb编程窗体、介面类。(Control other programs become their own child form, is a form vb programming, interface classes.)

一段局域网内网上聊天程序。这是一测试程序，更多的网络程序以后陆续发上来。-a LAN online chat program. This is a test program, more network programming onto successive fat.

说明：  2. 关于无线信道的多普勒谱，请回答以下问题： (1) 在某些无线信道中，多普勒频移会引起无线信道输出信号的混叠。请描述产生混叠的各种原因； (2) 无线信道中的多普勒谱有一种经典谱(classic spectrum)，请解释产生这种谱形状的机理； (3) 请用Simulink工具编写代码(S-Function方式)，产生一单径瑞利信道，其多普勒谱为经典谱，其中移动速率为120km/h。并请描述：自己用计算机产生的经典谱是正确的依据。(2. Regarding the doppler spectrum of the wireless channel, please answer the following questions: (1) in some wireless channels, doppler frequency shift will cause aliasing of the output signals of the wireless channel.Describe the various causes of aliasing; (2) there is a classic spectrum in the doppler spectrum in the wireless channel, please explain the mechanism of producing this spectrum shape; (3) please use Simulink tool to write code (s-function mode) to generate a single-path Rayleigh channel, whose doppler spectrum is the classical spectrum, in which the moving rate is 120km/h.And please describe: your own computer generated classical spectrum is the correct basis.)
