Simulation of Communication Principles Experiments using MATLAB/Simulink

This graduation project employs MATLAB's Simulink modeling and simulation tool to simulate communication principles experiments. As the first part of a series, it includes simulations of analog signal linear modulation/demodulation (AM, DSB, SSB) processes, scrambling and descrambling experiments, and low-pass signal sampling theorem verification. The paper covers MATLAB fundamentals, Simulink operation methods, and their applications in communication systems, with brief introductions to the underlying principles of each simulated experiment. Key implementation approaches involve using Simulink blocks for signal processing, modulation/demodulation algorithms, and sampling rate configuration. This project provides preliminary exploration for constructing a virtual laboratory for communication principles.
