Throughput analysis of ARQ selective-repeat protocol with time diversity in Markov channels

An ARQ selective repeat protocol with time-out mechanism is studied. Transmissions on both the forward and the reverse channels are assumed to experience Markovian errors and therefore the feedback is unreliable. Using renewal theory, exact results for the throughput of the protocol are evaluated. Simulation results, that confirm the analysis, are presented; an application to mobile radio is also discussed.
