The Achievable Rate Region of Wyner-Ahlswede-Körner Coding Problem for Mixed Sources

Abstract

The achievable rate region of Wyner-Ahlswede-Körner coding problem for mixed sources is investigated. Wyner-Ahlswede-Körner coding problem consists of two encoders and one decoder for two correlated sources. We derive the singleletter formula for mixed sources from Miyake and Kanaya’s general result. It clarifies the behaviour of the Wyner-Ahlswede-Körner achievable region for non-ergodic sources; depending on the property of side-information, the achievable regions are different.
