一个简单的dll库，封装了串口通信的链接，发送，接收。对这方面有兴趣的来学习。...

应用背景该程序可以应用在zigbee模块上，实现zigbee模块的相互通信，当然是通过射频方式而非z-stack方式。关键技术 能够实现多个模块之间的相互通信，并且能够使接收端在收到数据后自动转发数据，而且可以实现发射端也能接收到原来的数据，使得终端节点不仅具有终端的作用，还具有路由器的作用，更重要的是，它并非使用z-stack协议栈，运行速度更加的快而稳定。

利用vc实现的局域网文件传输，共分为客户端和服务器端两部分，该部分是文件传输的客户端，采用了TCP/UDP协议，可扩展到net网络传输！-use vc achieve LAN file transfer, is divided into client and server-side two, The file transfer is part of the client, using the TCP/UDP protocol, which can be expanded to net network transmission!

Linux下消息队列 用于进程间通信，有4个例程，可以实现 1.消息队列是消息的链表,具有特定的格式,存放在内存中并由消息队列标识符标识.  2.消息队列允许一个或多个进程向它写入与读取消息.  3.管道和命名管道都是通信数据都是先进先出的原则。  4.消息队列可以实现消息的随机查询,消息不一定要以先进先出的次序读取,也可以按消息的类型读取.比FIFO更有优势。     目前主要有两种类型的消息队列：POSIX消息队列以及系统V消息队列，系统V消息队列目前被大量使用。系统V消息队列是随内核持续的，只有在内核重起或者人工删除时，该消息队列才会被删除

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.
