Source Coding Simulation based on MATLAB
Abstract:
This paper describes the basic content of the communication system simulation, including the concept of a communication system simulation, digital transmission of analog signals and simulation, source coding concepts and MATLAB introduction of a visual simulation tool Simulink's. These powerful simulation software, making communication system design and simulation analysis process becomes relatively intuitive and convenient, which also makes the communication system simulation technology has been faster development.
For the communication system in some important areas, including sampling, quantization, principles, methods and procedures were coded in detail. On the basis of the theoretical understanding of the communication system on the use of the powerful MATLAB simulation capabilities, the design of specific sampling, quantization, coding principle simulation model. In the simulation model design process, the model design of specific structures, simulation processes and the simulation results are given specific and detailed analysis and explanation.
Finally, the research work is summarized and presented future work and research as well as prospects for the future.
