Study on interference problems between 5G base stations and adjacent frequency systems

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.
