蓝牙AUDIO的传输，可以发送音乐到耳机，基于WIDCOMM堆栈。

一个开放源码的免费的P2P客户端软件，用于文件交流，支持中文搜索。它和Neo-Modus公司的Direct Connect使用同一个通讯协议，但比它功能更加强大，可以同时登陆很多服务器。开放源码，绿色软件，也没有广告条。DC是分散服务器型的，服务器端也是免费的，因此适合同一个地域内的用户飞速交换文件。目前全世界有上万个服务器，通过DC共享的资料超过5,000,000GB。-a free open-source peer-to-peer client software for document exchange, support Chinese search. It Neo-Modus Direct Connect companies use the same communication protocol, but higher than its more powerful, while landing many servers. Open source software green, nor of the advertising. DC is decentralized server-based, server-side is also free, making it suitable to the region with a rapid exchange of user documentation. There are now more than 10,000 items of servers, DC by sharing information over 5,000,000 GB.

用VC实现PC并行端口数字信息的输入/输出.-With VC realize PC parallel port digital information input/output.

AWGN channel. Uses a file called BPSK (containing BPSK voltage levels) and adds gaussian noise to it. The noise is generated by box muller equation. Note: BPSK file was generated from BPSK modulator source: BPSK.c

In this simulink model , baseband 8-ary PAM detection is simulated .A half-sine pulse shaped PAM signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The 8-ary PAM signal transmitted is recovered at the detector output.

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:

本程序是我部开发的变频器CAShitc V1.0对应的上位机控制程序，通信采用的是Modbus协议，本人测试没有问题。请大家指教-This procedure was developed by the Department of inverter I CAShitc V1.0 PC corresponding control procedures, communications using the Modbus protocol, I test no problem. Please advice

gPRS源码 2008-07-14 起初的硬件有鑫旺焊回来之后缺少几个电容和1个100k的电阻，电容主要是电源处储能的功能， 100k的电阻是sim300的sim卡上的simpress管脚和VEXT之间的，没焊接时虽能找到网络，但是会出现 掉网的情况，把这些补上后，没有问题了。所以以前的经验电路还是比较准确的。电源处一定要稳定。 另外这次初始化完成后就立即发短信，第一个短信没有成功。并且在串口接收中发短信等待模块返回信息时， 返回了call ready，之后再发就可以发出去了。这应该是模块还没有准备好。Call Ready 当搜寻到网络后开始发送短信，有时会出现+CMS ERROR: 517这个错误，应该是sim卡还未准备好，所以当搜寻到网络 后需要在多等待一会。待模块发出Call Ready信号后，再操作。 2008-7-19 今天早晨在家准备调试一下这个模块发现始终找不到网络，用哪个卡都
