| Abstract: | Aiming at the interference analysis scenarios between geostationary satellite orbit (GSO) system and none GSO (NGSO) constellation system, an interference calculation method fused with the power allocation strategy is proposed, considering the characteristics of space links, beam service requirements and channels of NGSO and GSO systems. The objective functions and constraint conditions of the uplink and downlink are constructed. In a typical NGSO-GSO interference scenario with the network data of satellites actually registered by the International Telecommunication Union (ITU), the effects of typical power allocation strategies on the interference-to-noise ratio I/N are calculated and compared. The results show that for the downlink scenario, the proposed method with the power allocation strategy reduces the time percentage when interference to noise ratio exceeds the -12.2 dB limit by 0.24%-2.85% for GSO systems, and 0.77%-3.65% for NGSO systems. However, for the uplink scenario, this method does not significantly reduce the time percentage. |
