【摘要】 在星地一体化系统中,频谱共享可以有效提高频谱利用率,但也会造成不可避免的系统间干扰,严重影响星地一体化系统性能。本文将通过对星地一体化系统中的干扰机理进行分析,重点对系统间同频干扰进行分析,并对仿真结果进行比较,为星地一体化系统设计打下基础。更多还原

【Abstract】 In integrated satellite and terrestrial mobile system,frequency sharing can be effectively used to improve the utilization of the spectrum.However,it can also cause unavoidable inter-system interference and seriously reduce the performance of the integrated system.This paper will analyze the mechanism of interference in the integrated system,especially the inter-system co-channel interference,and compare the simulation results as the foundation for the design of integrated system.更多还原
