Abstract: This paper considers the queueing performance of a system that transmits coded data over a timevarying erasure channel. In our model, the queue length and channel state together form a Markov chain that depends on the system parameters. This gives a framework that allows a rigorous analysis of the queue as a function of the code rate. Most prior work in this area either ignores blocklength (e.g., fluid models) or assumes errorfree communication using finite codes. This work enables one to determine when such assumptions provide good, or bad, approximations of true behavior. Moreover, it offers a new approach to optimize parameters and evaluate performance. This can be valuable for delaysensitive systems that employ short block lengths. © 2010 IEEE.
