ABSTRACT
In this work, we extend a variable­length source cod­
ing theorem for discrete memoryless sources to ergodic
time­invariant Markov sources of arbitrary order. To ac­
complish this extension, we establish a formula for the
R'enyi entropy rate limn!1 H ff (n)=n. The main tool used
to obtain the R'enyi entropy rate result is Perron­Frobenius
theory. We also examine the expression of the R'enyi en­
tropy rate for specific examples of Markov sources and in­
vestigate its limit as ff ! 1 and as ff ! 0. Finally, we
conclude with numerical examples.
