With the 5G cellular base station testing and large-scale deployment of mobile communication operators. The interference of the 5G spectrum with the FSS Ext.C band (3.4-3.7 GHz) or the standard C band (3.7-4.2 GHz) will become more and more serious. To solve the problem of co-channel interference and adjacent-channel interference in the
In the 3GPP protocol,the overall spectrum resources of 5G can be divided into two FR (Frequency Range) FR1: The Sub6G frequency band is the main frequency band of 5G and is a low-frequency band，the frequency below 3GHz is Sub3G, and the remaining frequency bands are called C-bands. FR2: Millimeter wave is an
