Abstract: In response to the difficulties in teaching abstract theory caused by the interdisciplinary intersection of optoelectronic information science and engineering, this article proposes to apply MATLAB simulation technology to the topic design, system modeling, algorithm verification and other aspects of the graduation thesis. By constructing a theoretical verification system based on simulation experiments, the ability of“abstract theory simulation modeling engineering practice”can be advanced. Teaching practice has shown that this technology effectively deepens students'understanding of theoretical knowledge points, significantly enhances their comprehensive practical ability and innovative thinking, and improves the quality of their graduation thesis. It provides an operable practical path and experience reference for the teaching reform of optoelectronic information majors.
