In this paper, a modified form of the ARQ selective repeat protocol with timer control is studied. Transmissions on both the forward and the reverse channels are assumed to experience Markovian errors and therefore the feedback is unreliable. Feedback error recovery is made possible through the use of time diversity.Using results from renewal theory, exact results for the throughput of the protocol are evaluated. In order to overcome the complexity of the exact analytical technique, lower and upper bounds are developed. Simulation results, that confirm the analysis and document the tightness of the bounds are also shown, and a number of implementation issues are discussed. An application to mobile radio is also presented.It is shown that the use of an appropriate degree of time diversity makes it possible to approach the ideal protocol performance obtained with perfect feedback.
