Abstract

Various Automatic Repeat reQuest (ARQ) and Hybrid ARQ (HARQ) schemes have been employed to improve the performance of wireless communication systems operating in different environments. Various methods, some of them quite complex, have also been used to analyze the communication systems. In this report, we illustrate the simplicity of the transition diagram method when applied to the SR-GBN ARQ and HARQ schemes in fading environments and when diversity combining is employed. We derive the performance expressions for the schemes, which show that the SR-GBN HARQ scheme has better performance than the SR-GBN-ADP HARQ scheme.
