用于LDPC编码译码的仿真实现。包括随机生成校验矩阵、由校验矩阵产生生成矩阵、编码、加随机噪声、译码等内容。(For LDPC codec simulation. Including randomly generated check matrix, generated by the parity check matrix generator matrix, coding, plus random noise, such as decoding.)

说明：  GpRS数据中心代码，基本上实现了数据中心的大部分功能(GpRS data center code, basically realize the majority of the data center functions)

Microsoft Visual C++ MFC串口通信编程详解,主要介绍了用CreateFile()函数和WriteFile()函数读写串口的实例,以及设置 串口属性的实例. 在工业控制中,工控机(一般都基于 Windows 平台)经常需要与智能仪表通过串口 进行通信.串口通信方便易行,应用广泛. 一般情况下,工控机和各智能仪表通过 RS485 总线进行通信.RS485 的通信方式是 半双工的,只能由作为主节点的工控 PC 机依次轮询网络上的各智能控制单元子节点. 每次通信都是由 PC 机通过串口向智能控制单元发布命令,智能控制单元在接收到正 确的命令后作出应答. (Microsoft Visual C++ MFC serial communication programming explain CreateFile () and WriteFile () function to read and write the serial port of the instance, and set the serial port attribute instance in industrial control, IPC (generally based on the Windows platform) often need to communicate with the smart meter through the serial port serial communication easy and widely used normal circumstances, the IPC and intelligent instrument through RS485 communication RS485 communication is half-duplex, only as the primary node industrial PC turn polling network intelligent control unit child nodes. every communication from a PC via the serial port to issue commands to the intelligent control unit, intelligent control unit receives the correct command response.)

用VB编写的串口调试助手，附带51程序，大家可以学习，很经典，很地道(With VB serial debugging assistant, with 51 programs)

iec103 规约上位机源代码，喜欢的就下吧。(iec103 Statute of the host computer source code, like on the next bar.)

MFC写的2个程序，通过socket通信，上下位机的。上位机发送一个名字给下位机，下位机通过查询数据库取得电话号码传回上位机,带详细文档。(MFC write two procedures, through the socket communication, next-bit machine. PC to send a name to the next crew, the next crew by querying the database to obtain the phone numbers return PC)

this project simulate the voice communication between two subscriber stations in office scaled module and test the communications between them

用于监控PLC，针对的是modbus协议(monitoring PLC with modbus protocol)
