Abstract: The communication principle course is highly theoretical and abstract in content, traditional teaching mainly focuses on theoretical explanation, supplemented by confirmatory experimental teaching, to help students deepen their understanding of the content. This kind of teaching method that relies on verification experimental equipment is not flexible enough, which will affect students' classroom initiative and enthusiasm to a certain extent; At the same time, the laboratory box used in the classroom can hardly be applied in practical projects, which is not conducive to the cultivation of students' innovative ability and application ability. Therefore, this paper introduced MATLAB software into classroom teaching, and carried out open experimental exploration in the form of simulation. Practice has proven that after the implementation of classroom teaching reform, it effectively cultivates students' ability to analyze and solve problems, while deepening their mastery and understanding of knowledge.
