摘要
Abstract
This study examines the feasibility of coexistence between satellite direct-to-cell systems based on hopping beams and Fixed Satellite Service(FSS)systems.It analyzes coexistence scenarios between hopping beam satellite systems and FSS system as well as simulation research methods.Additionally,the study includes a simulation analysis of the downlink interference experienced by FSS system.Based on this,various interference mitigation strategies were evaluated for their effectiveness in protecting FSS system.This mainly includes geographic isolation,beam shut-off based on ephemeris or statistics information,and dynamic power control strategies based on interference level prediction.Final results indicate that,with appropriate interference mitigation measures,satellite direct-to-cell system based on hopping beams can successfully coordinate and coexist with FSS system.关键词
