Abstract
In this paper, we propose a novel approach to enhance the performance of irregular repetition slotted ALOHA (IRSA) protocol, which is called information coupled IRSA (ICIRSA). If transmission error happens, NACK is feedback and user chooses one of its replicas in the next frame and network coded it with the previous packet. As a result, the information from two independent frames are coupled and can be recovered together. Then, we employ density evolution analysis to evaluate the threshold of channel traffic load. After that, the performance of throughput and error probability are simulated. Simulation results show that the proposed IC-IRSA protocol outperforms conventional IRSA protocol significantly.
