一个用VC实现的聊天室程序，该程序是客户端和服务器端共用的。稍加修改可以做成网络数据收发。用的是winsock来实现网络通讯的-VC with a chat room procedures, the procedures are client and server shared. Little changes can cause network data transceiver. Used to the protocols of the communications network

《数字通信原理与技术》的随书PPT，希望对大家有所帮助-err

Simulates the BER for BPSK modulation in Rayleigh channel

卷积码编码，维特比解码程序，用c写的。应该有人需要-convolution encoder, Viterbi decoder, and c writes. Someone should be required

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.
