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.

数字调制技术一套的基础功能选择特定的调制方案。一般的基础功能是互相正交的。可以使用 "克施密特正交化" 过程派生的基础功能。一旦选择了基础功能，任何信号空间中的向量可以表示为基函数的线性组合。 在正交相移键控 （QPSK） 两个正弦波 (sin 和 cos） 作为基函数调制的。调制被通过不同相的基础功能，根据消息符号。在 QPSK，调制是基础，在那里有一个符号包含 2 位的象征。

在GSM通信系统中，Viterbi检测是一个及其重要的部分，许多的研究人员在这里花费了大量的心血。参考各种资料，我们总结得出以下Viterbi软输出算法，与传统的硬判决方法相比，可以提高2～3个db的增益：-In GSM communication systems, Viterbi detection is an important part of many researchers here spent a lot of effort. Reference to a variety of information, we summarize the following soft-output Viterbi algorithm, with the traditional hard-decision method, can be raised by 2 ~ 3 db gain:
