通信原理虚拟仿真平台研发OA

To overcome the limitations of time and location in the practical sessions of communication principles,enhance classroom teaching effectiveness,and help students better understand concepts and technical principles,this paper takes Amplitude Modulation(AM)as an example to study the development of a virtual simulation platform for communication principles.The AM modulation and demodulation system model was built using Simulink,and the AM system GUI was designed and developed using MATLAB App Designer.The GUI interface includes input parameters,output waveforms and spectra,system status display,as well as buttons to start simulations and close the interface.The MATLAB App or standalone application was generated in the MATLAB environment to facilitate use by both students and teachers.The waveforms and spectra displayed in the running results are correct,demonstrating that the AM system GUI developed in this paper is reasonable and feasible.It can be used for teachers'instruction and students'autonomous learning after class,effectively improving classroom outcomes and aiding students in consolidating their knowledge.
