Resource Minimization for Hybrid ARQ System With Real-Time Traffic in Time-Correlated Rayleigh Fading Channels

Free registration required

Executive Summary

Most studies on Hybrid Automatic Repeat reQuest (HARQ) with respect to rate adaptation have been focused on throughput maximization. However, for real-time traffic, resource minimization is a more efficient rate adaptation method in OFDMA-based systems. Moreover, most previous work have dealt with either slow or fast fading channel although practical wireless channels typically exhibit a time-correlated property. In this paper, the authors analyze the outage probability and average resource usage of HARQ with rate adaptation in a time-correlated channel model.
