Top1. Introduction
With the rapid development of mobile communication technology, the demand for talents is growing and its requirements are also getting higher and higher. Mobile communication is a major course of communication and electronic information, which has been attached great importance by higher school. But the wide range and many abstract concepts were involved in the course of mobile communication. As an important supplement, experimental courses can well make up for the shortcomings of theoretical study (Xu et al., 2018). The existing experimental environment plays an important role in mobile communication studies. At present, most mobile communication experiments in colleges are practiced by combining hardware test boxes with oscilloscopes, which contained several basic principles of wireless communication. However, it was difficult to keep up with the progress of mobile communication technology for the rapid iteration. Students can only observe limited waveforms and data through simple hardware wiring and oscilloscope debugging, instead of knowing the specific circuit composition and parameter settings inside the system. In addition, it is difficult to open to students all day and to maintain experimental equipment subsequently for the expensive cost.
The experimental course of mobile communication is an important part of training students' practical engineering abilities, which is beneficial to laying a foundation for future mobile communication-related practical work for students by understanding and mastering the knowledge and skills of mobile communication technology fully (Gao & He, 2021). However, there are many problems in the traditional experimental teaching of mobile communication course. Firstly, it is difficult to understand for experimenters because of relatively new theories containing some mathematical formulas in mobile communication course. The system experiments were insufficient since the teaching time was cut down. Secondly, most communication systems were updated quickly, and the actual system construction experiments were expensive. Many new generation mobile communication experiments cannot be opened in most ordinary universities because of the limitation of hardware funds. Thirdly, many mobile communication experiments in universities were a simple verification on the experimental box according to the experimental instructions. Students hardly understand the knowledge involving the whole process. It is difficult to expand students' innovative thinking and improve the teaching effect of mobile communication course. It is practicable to construct a virtual environment to complete experiments of mobile communication courses (Bayram & Caliskan, 2019). Some virtual simulation experiments do not sufficiently simulate the experimental parameters, which makes the experimental effect far from the real situation. Generally, some theoretical verifications were not emphasized in the course of virtual simulation, which led to a neglect to understand theoretical knowledge deeply.
The introduction of virtual reality technology into experimental teaching of mobile communication would be beneficial to expanding the traditional teaching model, enriching the teaching content of the mobile communication course, and improving students' learning interest. At the same time, it would stimulate students' learning enthusiasm, enable students to think deeply about the engineering principles and algorithms. By this way, students even may design and improve some systems' functions independently, improve students' innovative thinking, and thus improve the teaching effect of the mobile communication course (Cavanaugh et al., 2023; Degli et al., 2019). In order to cultivate students to better adapt to the high standard needs of society, a construction and management of mobile communication experimental study system based on virtual-real combination was improved to promote the integration of information technology and experimental study and further deepening of mobile communication practical study. By expanding experimental study in multiple dimensions and creating realistic and interactive experimental scenes, students can intuitively recognize and understand the relative theory and knowledge of mobile communication technology so as to enhance students' practical ability and innovation ability and achieve the goal of cultivating communication talents urgently needed by the society. It is important to apply the experimental study method of combination of virtual and real to the curriculum of mobile communication experimental study for the students in university especially in the post epidemic era.
