Abstract

Along with social progress and technological development, 5G technology has gradually matured and become the focus of research. 5G technology is related to all aspects of the future society, and each country has carried out fierce competition for the leading right of 5G technology. However, with the continuous progress of 5G technology, there are also many problems, among which the shortage of spectrum resources is of great concern. 5G spectrum is an important prerequisite to ensure the smooth development of 5G technology and system. Therefore, it is necessary to study the utilization efficiency of 5G spectrum, so as to improve the utilization efficiency of 5G spectrum and ensure the smooth operation of 5G system. Based on homomorphic encryption and encryption circuit, and with the help of principal component analysis, this paper tries to establish an evaluation method and system for the utilization efficiency of 5G spectrum, and carries out relevant detection on this system. At the same time, the application of 5G network technology in teaching practice is studied. On the one hand, it is beneficial to improve the efficiency of spectrum utilization, and on the other hand, it provides a certain theoretical basis for future research on relevant aspects.
