正交频分复用（OFDM）系统是一种多载波系统，其利用并行处理技术允许在许多的同时传输数据的密切隔开，正交子载波。快速傅立叶逆变换（IFFT）和快速傅立叶变换（FFT）在传统的OFDM系统被用于复用信号一起和解码信号在分别的接收机。本文研究的性能离散傅立叶变换正交基频分复用（DFT-OFDM）。

网络IP电话源代码 开机：打开监听服务，以便别人可以和你通话。 关机：关闭监听服务，已经接受的连接不受影响，你可以继续通话。 拨号：连接已经开机的机器，弹出对话框后必须输入对方的IP和端口，如果需要使用代理，请正确设置代理服　　　务器。 挂机：断开正在进行的通话。 开机后会显示你监听的IP和端口，别人可以通过这个IP和端口和你连接。 连接成功（你拨号连接别人或别人来连接你）后会显示对方的IP和端口。-IP telephony network boot source code : Open monitoring services, and so that other people can talk to you. Shutdown : Close monitoring services, has accepted the connection will not be affected, you can continue to talk. Dial-up : Connecting switched on the machine, pop-up dialog box appears to be imported each other"s IP and port, if the need to use the agent, the right to set up the proxy server. Coolness : disconnect the ongoing conversations. After boot monitor will show you the IP and port, the others through IP and port and connect you. Connecting success (your dial-up connection or other people to connect you) will show the other side of the IP and port.

应用背景实现串口通信基类，和扩展类，可以方便的实现串口通信。在基类上扩展了两个应用类，对于两个应用类实现相应通信协议的解析关键技术应用到了串口通信技术，RS232，并且对于实际应用进行了协议解析。通过基类的继承可以实现其它串口通信协议的解析与通信。很好的封装了串口通信应用。利用多线程技术实现了收发数据。
