An Effective Error Control Scheme for Satellite Communications

Abstract

The conventional go-back-N ARQ is inadequate for error control on satellite channels due to the large round-trip delay and high bit rate. The throughput efficiency of this system drops rapidly as the channel error rate increases. In this paper, a variation of the go-back-N ARQ is described. This variation reduces the effect of the round-trip delay, and hence increases the system throughput efficiency. Therefore, it may find applications in satellite communication systems or other systems where round-trip delay is large. Copyright © 1980 by The Institute of Electrical and Electronics Engineers, Inc.
