摘要:

针对5G基站与卫星地球站等邻频系统在频率共用、地理共存情况下出现的干扰问题,对5G基站被干扰情形进行了理论计算,对其他台站被干扰情形以及合法台站之间的共存进行了分析研究,提出了在出现同频干扰时能提升干扰定位效率的方法,包括使用实时频谱功能分析同频信号,运用5G NR解调功能对信号进行识别,以及结合车载同频多辐射源定位方法来确定干扰源的大致位置。

关键词: 5G, 同频干扰, 实时频谱分析

Abstract:

For the interference problems in frequency sharing and geographical coexistence between 5G base stations and the adjacent frequency systems such as satellite earth stations, the different situations consisting of the interferences to 5G base stations and the interferences to other stations were analyzed, and the solutions to improve interference positioning efficiency including analyzing the same frequency signal using real-time spectrum function, identifying the signal using 5G NR demodulation function, and locating the interference source combined with same-frequency multiple radio source positioning method were presented.

Key words: 5G, same frequency interference, real-time spectrum analysis
