Abstract
In this paper, by considering the effect of error correcting codes in addition to collision resolution, a novel probabilistic density-evolution analysis of the irregular repetition slotted ALOHA (IRSA) is proposed. Simulation results confirm that the proposed extension analysis can accurately recover the efficiency of the iterative successive interference cancellation (iSIC) scheme for a satellite Internet-of-Things (IoT) system endowed with an error correcting code, and therefore can be used to determine the corresponding optimal degree distributions.
