LAPB协议的实现源码，是X.25的基础。也可以称作为…

一个简单而全面的基于Modbus协议的范例程序，具有打开串口、发送数据、接受数据和CRT校验和检查数据，该项目中封装了Modbus类和SerialPort类，可以直接将这两个类导入工程中使用，通过调用Modbus类的接口来收发数据。。。谢谢大家支持！

Fundamental concepts of network Simulator-2

In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered at the detector output.-In this simulink model , baseband binary detection is simulated .A rectangular pulse shaped signal is given as input to the detector.The received signal is matched filtered and down-sampled .The effects of symbol timing offset can be seen by varying the phase of down-sampling operation.The binary signal transmitted is recovered at the detector output.
