再生式通信卫星转发器的研究进展

Research Progress of Regenerative Communication Satellite Repeaters

随着星上高速数据处理与交换的需求不断增加,再生式通信卫星转发器逐渐成为研究热点。概述了几种典型的再生式转发器国内外最新研究进展,指出了其信息处理、交换技术发展中存在的主要问题,包括多载波解调、吞吐量较低以及微波/光调制等,在此基础上提出了合适的补偿技术、星上半透明突发交换、光副载波调制以及波分复用等针对性的解决方法,可为我国卫星转发器设计以及星上信息处理、交换等关键技术研究提供参考。

With the increasing requirement of high rate on - board processing and switching, the regenerative communication satellite repeater is gradually becoming the focus of research. This paper introduces the recent re- search progress of several overseas and domestic representative regenerative repeaters, and points out main prob- lems in the development of information processing and switching including multi-carrier demodulation, low throughput and microwave/optical modulation. On this base, it gives corresponding solutions for compensation technology, on - board translucent burst switching, optical sub - carrier modulation and wavelength division multiplexing, which provides reference for the design of China＇s satellite repeater and research of on- board pro- cessing and switching.
