Abstract

An incremental redundancy hybrid ARQ (IRHARQ) scheme based on recently introduced Raptor codes is proposed and analyzed. A number of important issues, such as rate and power control, and error rate performance after each transmission on time varying binary-input, symmetric-output channels are addressed by analyzing performance of Raptor codes on parallel channels. A set of rules for incrementing redundancy and setting the signal power at each transmission in order to maximize the throughput are derived. The theoretical results obtained for random code ensembles are tested on several practical code examples by simulation. Both theoretical and simulation results show that Raptor codes are suitable for HARQ schemes.
