In mathematics, a Markov information source is an information source whose underlying dynamics are given by a stationary finite Markov chain.

Formal definition

An information source is a sequence of random variables ranging over a finite alphabet Γ, having a stationary distribution.

A Markov information source is then a (stationary) Markov chain M, together with a function

that maps states in the Markov chain to letters in the alphabet Γ.
