A Novel Approach for Modeling a Hybrid ARQ (Automatic Repeat Request) Based on the Hidden Markov Model

IEICE Transactions on Communications, 2005
In this letter, we propose a novel approach for use in the analytical modeling of the overall performance of a Hybrid ARQ (type I and II) together with arbitrary channel model, based on Hidden Markov Model (HMM). Using the combined HMM model developed for involved ARQ protocols with the finite state channel model, such critical performance measure as ...
