摘 要: 利用MATLAB平台的SIMULINK功能编写了一套QDPSK通用功能模块库，并在此基础上进行了多项可视化仿真,较 好地显示了数字通信的工作方式和优越性，以及采用SIMULINK进行仿真的良好的演示效果，为QDPSK数字通信系统的研究提 供了一个较好的软件平台。(Abstract: This paper gives a group of module library for digital communication function applying MATLAB’ s SIMULINK function， and offer a group of software to perform the visualizing simulation. The software perfectly shows the advantage and the process of normal digital communication. More over, it provides a software base for further study on QDPSK Digital communication.)
