Summary: 
In this paper, we analyze the throughput of the Stop-and-wait and Go-back-N ARQ schemes over an unreliable channel modeled by the two-state Markov process. Generally, in these states, block error probabilities are different. From analytical results and numerical examples, we show that the throughput of the Stop-and-wait ARQ scheme only depends on overall average error probability, while that of the Go-back-N ARQ scheme depends on the characteristic of the Markov process.
