Exact Common Information and Exact Channel Synthesis for Correlated Discrete Sources

Open at sourcePDFDOICite

Abstract

In this paper, we provide a single-letter characterization of the exact common information for a pair of correlated discrete sources, as well as a single-letter characterization of the admissible region for the shared randomness rate and the communication rate in exact channel synthesis.
