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

主要实现接受和发送信息的功能。气动并属兔对方IP后单击连接按钮，来实现，能很好说明。NET在中Socket编程技术 -Mainly to receive and send messages to achieve functions. Pneumatic and other IP is a rabbit and click connect button, to achieve, can be a very good note. NET programming in Socket

WINDOWS串口编程，调试程序第一部分-WINDOWS serial programming, the first part of the debugger

We investigate the case of independent Rayleigh faded paths between antenna elements and find that with high probability extraordinary capacity is available. Compared to the baseline n = 1 case, which by Shannon’s classical formula scales as one more bit/cycle for every 3 dB of signaltonoise ratio (SNR) increase, remarkably withMEAs, the scaling is almost like n more bits/cycle for each 3 dB increase in SNR. To illustrate how great this capacity is, even for small n, take the cases n = 2, 4 and 16 at an average received SNR of 21 dB. For over 99 of the channels the capacity is about 7, 19 and 88 bits/cycle respectively, while if n = 1 there is only about 1.2 bit/cycle at the 99 level. For say a symbol rate equal to the channel bandwith, since it is the bits/symbol/dimension that is relevant for signal constellations, these higher capacities are not unreasonable. The 19 bits/cycle for n = 4 amounts to 4.75 bits/symbol/dimension while 88 bits/cycle for n = 16 amounts t

今年上半年我为现公司一款流量计产品编写的上位机Modbus通讯程序（下位机程序也是我用C编写的，由于受到法律许可限制，在此不能上传，不过在将来我会把设计思路传上共享），包括自创的Modbus协议的Delphi实现及其完整调用，还有一份我编写的该产品的完整的Modbus协议说明书，非常有参考价值。-First half of this year the company I am now prepared a flowmeter products PC Modbus communications procedures (the procedures are under-bit machine I use C prepared, because of license restrictions by law, can not upload here, but I will in the future design ideas Chuan-share), including self-Modbus protocol Delphi to achieve their full call, there is also a preparation of the product I am a complete Modbus protocol specification, a very good reference material.
