微软亚洲研究院论文：3G网络视频传输中服务质量自适应的资源分配

In this simulink model , BPSK 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 , BPSK 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.

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.

WLAN的ofdm仿真系统代码，包括信道估计、同步等-WLAN ofdm simulation system code, including channel estimation, synchronization, etc.

windows系统，qt creator2.4.1基于qt4.7.4（32bit），用多线程实现串口通信，编译成功，注意下载后，要选择你下载路径下的工程文件夹昨晚编译路径，不然无法修改调试。还有就是这个路径里不能有中文字符，不然无法编译成功。

串口通信的源码，可以在vc6.0编译工具上编译通过，是学习串口通信的好源码。
