This article examines the queueing performance of communication systems that\ntransmit encoded data over unreliable channels. A fading formulation suitable\nfor wireless environments is considered where errors are caused by a discrete\nchannel with correlated behavior over time. Random codes and BCH codes are\nemployed as means to study the relationship between code-rate selection and the\nqueueing performance of point-to-point data links. For carefully selected\nchannel models and arrival processes, a tractable Markov structure composed of\nqueue length and channel state is identified. This facilitates the analysis of\nthe stationary behavior of the system, leading to evaluation criteria such as\nbounds on the probability of the queue exceeding a threshold. Specifically,\nthis article focuses on system models with scalable arrival profiles, which are\nbased on Poisson processes, and finite-state channels with memory. These\nassumptions permit the rigorous comparison of system performance for codes with\narbitrary block lengths and code rates. Based on the resulting\ncharacterizations, it is possible to select the best code parameters for\ndelay-sensitive applications over various channels. The methodology introduced\nherein offers a new perspective on the joint queueing-coding analysis of\nfinitestate channels with memory, and it is supported by numerical simulations.\n
