Today it is more and more important for those students whose major are electronic information technology to master the knowledge aboutmunication technology. Not only it is their profession require but also the demand of our society. After learning the textbook about munication principle, I know some basic knowledge about munication, but I seldom have a simulation experiment about it. This thesis will focuses on the munication principle based on the matlab graphical interactive experiments platform(MATLAB GUI), so that we can have a indeep understand about the basic knowledge of munication principle, it will facilitate our further study about on the munication technology. This article emphasize how to use of MATLAB software to design the basic principle of simulation experiment platform and its function based on munication principle knowledge. I design multiple interface in the MATLAB software which provides a graphical user interface GUI. That MATLAB GUI project about munication principle will help us have a deep understand what we have learned the basic knowledge about munication principle. MATLAB interface design of GUI munication principle experiment simulation platform has the advantages of simple structure, integration, allows the operator to stick out a mile of the principle of the munication of knowledge ,and it has demonstrated strong, simple and
