Therefore, this paper explores the research-oriented teaching mode of “Principles of Communication” under the background of new engineering, promotes the iteration of teaching mode by improving teaching methods and updating teaching ideas. While strengthening students’ practical teaching and improving their practical ability, it fully combines the simulation analysis and experimental teaching links related to communication principles to introduce new communication technologies and constantly update the teaching content. To provide students with quality learning experience and harvest.
