摘要

卫星在ka波段的宽带接入目前受到频谱可用性的限制。目前正在提议在ka波段频谱上运行的高通量卫星系统,该频谱分配给固定卫星业务(FSS)和固定业务(FS)。本文提出了一种利用17.7至19.7 GHz频段双重使用的数据库方法。利用真实的数据库和适当的传播模型分析了来自FS的干扰。还评价了几个欧洲联盟(EU)国家的数据库统计数据。讨论了使用精确地形剖面和精确传播模型的重要性,并给出了一些结果。

Analysis of interference between terrestrial and satellite systems in the Band 17.7 to 19.7 GHz
Broadband access by satellite in the Ka-band is currently constrained by spectrum availability. Very high throughput satellite systems are being proposed that operate in the Ka-band spectrum that is allocated to both Fixed Satellite Services (FSS) and Fixed Services (FS). This paper addresses a database approach to exploiting the dual use of the band 17.7 to 19.7 GHz. Interference from the FS has been analysed using real data bases and appropriate propagation models. Database statistics for several European Union (EU) countries were also evaluated. The importance of using accurate terrain profiles and accurate propagation models are discussed and some results shown.
