Coexistence studies between LTE system and earth station of fixed satellite service in the 3400–3600 MHz frequency bands in China

LTE system will share the same frequency band with fixed-satellite service (FSS) in 3400 ~ 3600 MHz, which has been identified as one of the candidate bands for the future development of mobile systems. In this paper, deterministic analysis and Monte Carlo simulation are adopted to study the co-existence of two systems in 3400~3600 MHz based on the FSS parameters in China. In deterministic analysis, three types of interference, which are co-channel interference, adjacent channel interference and overdrive, are studied. Then interference probability of FSS earth station is simulated using Monte Carlo simulation, which is based on the result of deterministic analysis. The analysis result shows that LTE frequency offset from edge of FSS channel should be above 10MHz for downlink and above 5 MHz for uplink in China.
