[0042] In order to better understand the contents of the present invention, an example is given here.
[0043] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0044] Such as figure 1 As shown, the terrestrial mobile communication system IMT-T is composed of several scattered ground radio frequency terminals. The ground radio frequency terminals include base stations and ground mobile terminals. The base station is denoted as BS, and the ground mobile user terminal is denoted as UE; S is composed of multiple multi-beam satellites in the space segment, ground gateway stations and several satellite mobile user terminals; both the IMT-S system and the IMT-T system adopt frequency division multiplexing technology, and the IMT-T system and the IMT-S system are in the same When the same frequency is shared within the area, the ground radio frequency terminal will interfere with the uplink of the IMT-S system.
