Coexistence of mobile-satellite service system with mobile service system in shared frequency bands

摘要

Interference scenarios and a methodology between mobile-satellite service (MSS) system and terrestrial mobile service (MS) system in a co-frequency environment are established. Taking into account a practical deployment situation for both systems, computational simulation of interference in terms of the percentage increase in equivalent satellite link noise temperature (94;T/T) and the ratio of carrier power to interference power (C/I) is performed to evaluate the co-frequency interference from the MS system into the MSS system. The methodology and results could be used for planning an MSS deployment without an unacceptable interference impact from MS.
