Chinese RFC documents, without translation, the right to study very helpful!

DNP3 Object Library Documentation (*.doc extension) 2.1 GENERAL This section describes the basic rules for the declaration of information elements. These rules have been derived from the IEC TC57 870 series of standards or drafts. These rules provide an unambiguous means of describing and representing data irrespective of its origin. Device profile documents are used to indicate the exact origin and meaning of the data object for each telecontrol device.

一个用VC实现的聊天室程序，该程序是客户端和服务器端共用的。稍加修改可以做成网络数据收发。用的是winsock来实现网络通讯的-VC with a chat room procedures, the procedures are client and server shared. Little changes can cause network data transceiver. Used to the protocols of the communications network

ASK通信编程仿真源程序-ASK communication simulation programming source

matlab实现QPSK调制,分别给出了相位选择法和I Q两路正交调制相加发实现QPSK调制，给出了QPSK调制后的功率谱密度。

也没别的就是为了要积分，里面有RTSPserver ,RTSPclient  虚拟mediaserver, 大家可以先开mediaserver 然后 在mediaserver文件夹下面放入 你要播放的视频或音频 然后在testprogs 里面的 OpenRTSP 可以运行， 用CMD可以查看 PACKET收信

测试脚本是自动化测试的核心，数据驱动自动化测试框架的脚本开发过程是以模块化和数据驱动为基础，本代码结合实际视频服务器访问过程为指导，结合QTP的专家视图开发环境来编写实现了数据驱动自动化测试框架的脚本。

In this simulink model , QPSK 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 , QPSK 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.

A good utility (sourcecode) to start to send data to a SPI memory Atmel AT45db.

用MSComm进行串口编程，已在Delphi6.0环境下编译通过-MSComm carried out using serial programming environment has been compiled through Delphi6.0

类似MSN的即时通信工具,代码在vc6.0下调试通过-Similar to MSN
