ARQ Error Control on Satellite Channels with High Error Rates.
Abstract
Some variations of the automatic repeat-request (ARQ) System of error control, the widely used system on terrestrial links, are considered suitable even for satellite links. The major problem is that the large round trip delay associated with satellite channels reduces the throughput, more drastically under high error rate conditions. Further, ground segments that usually accompany satellite circuits at both ends introduce bursts of errors, during which block error rates tend to be quite high, bringing down the throughput to very low values. In the report, some of the implications of using ARQ for error control on satellite links are briefly explained and some schemes that modify the currently used variations of ARQ are suggested with a view to obtain larger throughput under high block error rate conditions.
