Performance Analysis and Comparison of HARQ Protocols Based on Outage Probability in Wireless Communication Networks
Fan Wang, Suoping Li, Zufang Dou · Procedia Computer Science · 2019
Hybrid Automatic Retransmission reQuest (HARQ) protocol can effectively compensate the signal transmission error caused by complex time-varying channels and multi-path effects of wireless communication networks. This paper analyzes and compares the principle and system performance of three HARQ protocols from the perspective of system outage probability, and the expressions of system throughput and energy efficiency are derived by establishing a one-dimensional Discrete Time Markov Chain (DTMC) and calculating the steady-state distribution. MATLAB numerical simulations are applied to evaluate and compare the performance superiority among three HARQ Protocols.
