这是有关锁相环的一些必用知识.希望能对大家有所帮助哈

一个简单的SIPproxy，拿来给大家用，很多终端都能注册-SIPproxy a simple, we used to use a lot of terminals would be registered

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.

此仿真程序是目前论坛里面最完整的仿真源码，并且经本人调试运行，完全没有错误，有很高的研究价值。为各位搞仿真和做OFDM系统相关论文的研究生，而没有全面仿真程序的人提供本程序。此程序包含52个仿真模块，可以仿真出52个仿真图。-This simulation program is the forum inside the most complete source of emulation and debugging, as I run, there is no error, has high research value. For you to do engage in OFDM system simulation and related post-graduate theses, and no comprehensive simulation program provide the program. This program contains 52 simulation module can be a simulation simulation Figure 52.
