libsmi的使用手册及网站，著名的德国MIB读取软件，非常好用-libsmi the use of manuals and websites, a prominent German MIB read software, very easy to use

本文讲述了linux操作系统下网络编程的相关步骤。 　Linux的源码里，网络接口的实现部份是非常值得一读的，通过读源码，不仅对网络协议会有更深的了解，也有助于在网络编程的时候，对应用函数有更精确的了解和把握。 　　本文把重点放在网络接口程序的总体结构上，希望能作为读源码时一些指导性的文字。 -This article describes network programming under linux operating system of the relevant steps. Linux source code, the network interface to achieve most of it is very worth reading, by reading the source, not only on the network will have a deeper understanding of the agreement, will also help in network programming when the application has a more precise function understanding and grasp. This article focused on the network interface on the overall structure of the procedure, hoping for some guidance when reading source code of the text.

在第1章中，我们首先讨论在使用和不使用M F C的情况下创建一个窗口，以便清楚地了解 M F C是如何工作的。M F C窗口既可以由属于M F C的C + +类创建，也可以由一个早于并存在于 M F C之外的非C + +窗口类创建。我们将进一步观看窗口类并讨论那些由Wi n d o w s操作系统提 供的窗口类。最后，再看看M F C应用程序中都有什么。-In Chapter 1, we first discuss the use and does not use MFC create a window to a clear understanding of how the work of MFC. MFC window can belong to MFC from the C++ Type create, you can co-exist as early as by an outside non-MFC is C++ Window class to create. We will further watch window class and discussed by the Wi ndows provided by the operating system window class. Finally, take a look at MFC application has what.

In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.-In this simulink model , 16-QAM modulation and demodulation is simulated .A square root raised cosine pulse shaped signal is modulated and given as input to the demodulator.The received signal is demodulated and given to the detector where it is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The signal transmitted is recovered at the detector output.
