An adaptive incremental redundancy selective-repeat ARQ scheme for finite buffer receivers
Slim Kallel, Cyril Leung · 1991
An incremental redundancy selective-repeat ARQ (automatic-repeat-request) scheme, called the AIR (adaptive incremental redundancy) scheme, for use in systems with limited buffer receivers, based on the use of punctured convolutional codes, is introduced. Its throughput is compared to that of E. J. Weldon's (1982) scheme and a type-II ARQ scheme studied previously by the authors (1990). The AIR scheme is found to have a relatively good throughput over a wide range of channel conditions, thus making it attractive for use on time-varying channels.>
