General formulas for Csiszar's source coding cutoff rates

In this work, Csiszar's (1995) fixed-length source coding /spl beta/-cutoff rates are investigated for the class of arbitrary discrete sources with memory. It is demonstrated that the limsup and liminf Renyi entropy rates provide the formulas for the forward and reverse /spl beta/-cutoff rates, respectively. Consequently, new fixed-length source coding operational characterizations for the Renyi entropy rates are established.
