Abstract:

In view of the lack of spectrum resources, the deterioration of the electromagnetic environment, the uneven distribution and the high degree of correlation in space, time and frequency domain, a spectrum resource management and control system based on big data analysis is proposed. The system consists of spectrum monitoring and storage, data analysis and management and control center composed of three functional modules. Firstly, the distributed data acquisition framework is used to collect spectrum information and GPS information. Then, the use of big data analysis technology to predict the next time the use of spectrum resources to detect available channels to improve the efficiency of spectrum monitoring and optimize the spectrum monitoring strategy; finally, use the control center to manage spectrum usage rights of different levels of users. The simulation results show that the system can effectively deal with the massive spectrum data and improve the utilization of spectrum resources.
