Jitter is extremely important in systems using PLL-based clock drivers. The effects of jitter range from not having any effect on system operation to rendering the system completely non-functional. This application note provides the reader with a clear understanding of jitter in high-speed systems. It introduces the reader to various kinds of jitter in high-speed systems, their causes and their effects, and methods of reducing jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.

上面都是C版本，最后给一个linux下as86编译的汇编版本. 就是用串口通讯线将两台机子用串口连起来进行通讯，最简单的。比如在a机上输入一个字符，在b机上能显示出来-above are C version linux finally given a clock under the compilation compiler versions. Serial communication is to use two machines will be used Serial Link together communications, the most simple. For example, in a plane into a character, b plane will display

这是一个定点的多带OFDM物理层发射机/接收机模型,共122个子载波，22个导频，采用QPSK调制,5/8前向纠错码(删余卷积码.)-This is a sentinel of the multi-band OFDM physical layer transmitter/receiver model, a total of 122 sub-carrier. 22 pilots, using QPSK modulation, 5/8 prior to the error-correcting code (I delete convolutional codes.)

在VC++6.0中用MSComm控件编程，可以实现串口接收数据和发送数据，数据分别显示在接收框和发送框中。 如何建立工程：建立新文件夹，将文档用WINZIP解压后，双击 Scommtest.dsw 即可在VC6.0中打开工程文件。作者主页上有详细编程说明，每一步都列出来了，可以参考。-In VC++ 6.0 using MSComm control programming, you can realize the serial receive data and send data, data were displayed on the receiver box and sent box. How do I create a project: create a new folder, and will extract the files using WINZIP, double-click Scommtest.dsw can open in VC6.0 project file. Author home page has a detailed program description, list each step, and can refer to.
