摘要
Ka频段卫星通信的抗雨衰技术能够有效降低Ka频段的雨衰影响,提高Ka频段信号传输质量。重点讨论了分集技术和自适应技术,综述了现有的抗雨衰技术及其之间的联系,总结了热点研究方向,为今后抗雨衰技术的研究奠定了基础。
A lot of research effort has been spent on fade countermeasures so as to reduce rain attenuation, and improve satellite communication quality in Ka-band. This paper discusses diversity and adaptive techniques, and summarizes the fade countermeasures relation. It gives a review of current research in order to investigate future research issues.
