5G通信系统同步信号抗干扰能力研究

5G network has the advantages of wide coverage, large capacity, high speed, low delay, etc. However, most 5G communication systems have fixed base stations, which are vulnerable to human malicious strong interference. The interference has a great impact on the communication system, which will reduce the system performance and affect the communication quality. Therefore, it is of great significance to study the anti-interference capability of the communication system. In addition, millimeter wave has good directivity, strong reliability and high transmission efficiency, and has been widely used in 5G communication services. In the case of high-speed movement, the increase of frequency band will bring greater Doppler frequency offset. In the strong interference and high dynamic scenarios, the performance of time-frequency synchronization algorithm needs further analysis. Therefore, this paper focuses on the anti-jamming capability of synchronous signals of 5G communication systems in high dynamic scenarios.
