| Abstract: |
| With the increasing requirement of high rate on-board processing and s
witching, the regenerative communication satellite repeater is gradually becomin
g th
e focus of research. This paper introduces the recent research progress of se
veral overseas and domestic representative regenerative repeaters, and points ou
t main problems in the development of information processing and switching incl
uding
multicarrier demodulation, low throughput and microwave/optical modulation.
On this base,it gives corresponding solutions for compensation technology, on-bo
a
rd translucent burst switching, optical sub-carrier modulation and wavelength di
vision multiplexing,which provides reference for the design of
China′s satellite repeater and research of on-board processing and switching. |
