Such sharp opposition to the two requirements, only through the use of powerful puteraided analysis and design techniques and tools to achieve. Modern puter science and technology rapid development, has developed a new generation of visual simulation software, the powerful, making the design of the munications system simulation and analysis process is relatively straightforward and convenient. The thesis introduces the design of simulation software puter experiment of digital munication principle in the course of baseband transmission system. The main content of this thesis is to analyze the digital baseband transmission system using SIMULINK dynamic system simulation platform for MATLAB, on the basis of establishing simulation model, description, and analysis of simulation results. The digital baseband signal transmission system consists of filter (channel signal forming device), channel, receiver filter and sample sentence position, in the thesis, firstly, a detailed analysis of the digital baseband transmission system, obtains the theory value. Then through the analysis of the system, design the overall simulation block diagram, use MATLAB for modeling and encapsulation of each sub system, established the digital baseband transmission system simulation model, simulation model and the test, the basic simulation results are consistent with theoretical value.
