无线通信系统中的空时编码的仿真程序。多天线发送，多天线接受系统。衰落信道。...

压缩包内是基于c++编程的485通讯的程序，包括电路原理图和源程序代码-Compressed packet is based on the c++ programming of the 485 procedures, including circuit schematics and source code

非常详细的modbus规范介绍，有串口的也有基于tcp的。。。。一书在手，modebus不用愁。。。。MODBUS标准分为三部分。第一部分（“Modbus协议规范”）描述了MODBUS事物处理。第二部分（“MODBUS报文传输在TCP/IP上的实现指南”）提供了一个有助于开发者实现TCP/IP上的MODBUS应用层的参考信息。第三部分（“MODBUS报文传输在串行链路上的实现指南”）提供了一个有助于开发者实现串行链路上的MODBUS应用层的参考信息。-very detailed Modbus standard, a serial port is based on the tcp. . . . A book in hand, do not have to worry about modebus. . . . MODBUS divided into three parts. The first part ( "Modbus protocol specification") describes the MODBUS handle things. The second part ( "MODBUS Packet Transmission in TCP/IP Implementation Guide"), provides a help developers to implement TCP/IP on the application layer MODBUS reference information. The third part ( "MODBUS Packet Transmission in the serial link achieve Guide"), provides a help developers achieve serial MODBUS link on the application layer of reference information.

开放源码的smpp协议开发包，最新版本0.3.6，有详细文档及示例。-open-source agreement Development Kit, the latest version through a detailed documentation and examples.

用S7-200PLC的自由口模式和VB中的MSComm控件方便地实现了计算机与S7-200（CPU224）PLC的通讯。计算机作为主站,用户通过计算机可以方便地设置房间的控制指令并向PLC发出控制或监测命令， PLC作为从站来响应计算机发送的指令并采取相应的动作并将房间的电、水、热信息发回到计算机。用户可以通过电脑屏幕实时地监视到房间的电、水、热信息并进行相应的处理。-with S7-200PLC the Free Port Mode and the VB MSComm to realize a trap Computer and S7-200 (CPU224) PLC communications. Computer as a master station, Computer users can easily set up control rooms PLC issued directives to control or monitoring orders, PLC as from the station to respond to orders sent by the computer and take corresponding action will be room for electricity, water, Heat fat information to the computer. The user can screen real-time surveillance of the room electricity, water and heat information and handled accordingly.

Delphi环境下用MSComm控件进行串口编程，已在Delphi6.0下编译通过。-Delphi environment using MSComm controls serial programming, has been compiled through under Delphi6.0.

利用labview实现串口通信。先安装visa驱动包， 再就是visa read 作用是从串口读取数据，这里面有个read buffer ，从串口读取的数据 visa write向串口写入数据或者是命令 还有visa close 结束串口读取数据，目的是读完数据后，释放串口资源

压缩感知关于Xampling硬件实现的代码，恢复算法用的是OMP重构，观测矩阵用的是贝努力测量矩阵。是当前压缩感知做得最好的以色列 做得程序，其中的CTF模块应该重点学习

这是一个232转485的实用电路图，大家可以 参考一下，如果有不对的地方可以提出来，我再做修改，欢迎大家前来查看，谢谢！
