Abstract

To reduce the impact on the performance of satellites caused by space radiation environments, redundant structures are introduced into hardware design. Meanwhile, it brings in a new trouble, that is, a great deal of hardware resource is consumed. To overcome the problem, a lot of methods are proposed, one of which is using the residue number system (RNS). The RNS is proved to be suitable to all linear systems in this paper. Since the main modules of Bent-pipe (BP) satellites such as beam forming, finite impulse response (FIR) filters can be approximated to linear systems, RNS becomes an effective way to reduce the area overhead of hardware in BP mode satellite communication systems.
