Abstract: This article explores the relation between queueing behavior and coderate selection for digital communication over correlated erasure channels. The focus is on nonasymptotic system analysis, with finite blocklengths and nonvanishing probabilities of decoding failure. The transmit buffer is assumed to possess a given initial distribution and performance is evaluated in terms of the time required for the queue to become empty. Special attention is given to channel memory and its impact on the decoding process at the receiver. The system is ultimately defined in terms of a finitestate erasure channel. Using a Markov structure, the evolution of the transmit buffer is characterized and the distribution of the firstpassage time to an empty queue is obtained. The proposed methodology is employed to optimally select coderate. This provides new insights on the natural tradeoff between error protection and data content in the finite blocklength regime. ©2010 IEEE.
