Ju l 2 00 7 On the error exponent of variable - length block - coding schemes over finite - state Markov channels with feedback ∗


The error exponent of Markov channels with feedback is studied in the variablelength block-coding setting. Burnashev’s [5] classic result is extended and a single letter characterization for the reliability function of finite-state Markov channels is presented, under the assumption that the channel state is causally observed both at the transmitter and at… (More)
