摘要

研究了混合源下Wyner-Ahlswede-Körner编码问题的可达率区域。Wyner-Ahlswede-Körner编码问题由两个相关源的两个编码器和一个解码器组成。我们从Miyake和Kanaya的一般结果推导出混合源的单字母公式。它阐明了非遍历源的Wyner-Ahlswede-Körner可达区域的行为;根据边信息的性质，可实现的区域是不同的。

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

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.
