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.

Synapse串口同步库。功能有：它不是控件，而只是代码库。适合编写控制台应用服务或其它应用；不需要安装；读写数据的方法和Synapse提供的TTCPBlockSocket一样；支持MODEM的AT指令；支持RTS驱动的通讯（例如：RS-485适配器）。功能无限制。源代码：包含。适用语言：CB3 CB4 CB5 D2 D3 D4 D5-Synapse serial synchronous library. Function: it is not control, but only code base. Suitable for the preparation of the console application services or other applications do not need to install read and write data and Synapse as provided TTCPBlockSocket support the AT commands MODEM support RTS-driven communications (for example: RS-485 adapter). Features unlimited. Source code: contains. Applicable language: CB3 CB4 CB5 D2 D3 D4 D5

OFDM的一种频分复用方案。把频谱分成两个部分，一部分频谱用同频复用，一部分频谱采用复用因子为3，这就是reuse partitioning,或者叫部分频率复用技术（Fractional Frequency Reuse)。频率复用因子表示一个频率复用簇当中的频点的数量。复用因子越大，表示复用距离越大。代码对FFR进行了仿真，适合初学者。
