利用NI的动态链接库编写的GPIB通信实例，能够初始化8920A测试仪器，能够发送相关的控制命令来控制仪器的工作状态，还能够读取仪器的测试数据，采用标准的gpib32动态链接库，程序通过耐久性测试，在断电之后再通电仍然能够不用关闭软件而直接连接通信。之前是vc的例子调用，在此改为了利用delphi调用相关函数，发送相关控制命令一样实现了delphi的gpib通信程序。

这个也是关于空间谱的matlab 挺好的 可以-This is on the spatial spectrum of matlab can be quite good

systemview的2DPSK调制解调，这是个svu文件，对理解使用systemview有用，对2dpsk的课程设计有用。包括2dpsk系统的调制和解调过程。

ymodem协议源码实现 -The source of ymoderm protocol

虽然Windows下可视化开发工具如VC、Delphi、C＋＋ Builder等都有专用的定时器控件Timer，而且使用很方便，可以实现一定的定时功能，但最小计时精度仅为55ms，且定时器消息在多任务操作系统中的优先级很低，不能得到及时响应，往往不能满足实时控制环境下的应用。不过Microsoft公司在Win32 API函数库中已经为用户提供了一组用于高精度计时的底层函数，如果用户使用得当，计时精度可到1ms。这个计时精度、对于一般的实时系统控制完全可以满足要求。现将由C＋＋ Builder 4.0提供的重新封装后的一组与时间相关的主要接口函数（函数名、参数、功能与Win32 API基本相同）说明如下： -visual development tools such as Visual C++, Delphi, C++ Builder and others all have dedicated Timer timer control, but it is convenient. can achieve a timing function, but only the minimum time of 55 ms accuracy. Timer news and multi-task operating system in the low priority that is not to respond in a timely manner, often fail to meet the real-time control environment applications. However, Microsoft Corporation in the Win32 API function has been to provide the user with a group for high-precision the bottom was a time function, if the user is properly utilized, time accuracy can be a ms. Accuracy this time, and for most of the real-time control system can meet the requirements.
