Course：Comprehensive Experiments for Communications

Credit(s)：Two credits，36 hours

Course Description：The module of comprehensive experiments for communications includes two parts: Simulation of communication systems and comprehensive hardware experiments. In the simulation part, students will learn the simulation skills for modern communication systems, including simulation models for signals and systems, generation and processing of random signals, graphical methods in simulation,Monte Carlo and semi-analytic methods, modeling and simulation of time-varying systems, and methodology for simulation of a wireless system. The goal of the comprehensive hardware experiments part is to enable students to have a thorough understanding of the developing platform of the hardware on the current communication, multimedia, and other information system components. From the principle and experiments, the students should have certain practical ability and have the ability to design, the preliminary debugging communication,multimedia information system on the DSP/FPGA/ARM hardware platform. Not only familiar with the basic principles of the system hardware development and the basic design ideas, the students should improve the ability of analysis of requirements with the corresponding application platform. At the same time,through the experiments of  DSP/FPGA/ARM hardware development platform, the students should have certain hardware design, programming, and debugging abilities.
