Abstract: In view that there are some complex concepts which are difficult for students to understand in the massive multiple input multiple output (mMIMO) technology teaching, which is a part of new wireless techniques in the course of wireless communication theories and techniques, and according to the requirements of the course teaching reform, a mMIMO technology teaching platform is constructed by using MATLAB APP designer tool software. In this platform, by setting specific parameters, the graduate student can perceptually understand the key issues of mMIMO technology, such as channel hardening and low complexity signal detection, with the visual simulation results. The feedbacks from the teaching practice indicated that the real-time demonstration of mMIMO technology teaching platform enhances the interactivity of teaching practice, and improves the graduate students’ interest in theoretical learning and innovation ability.
