The capacity of a class of broadcast channels 论文

摘要

The capacity region is established for those discrete memoryless broadcast channels <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">p(y,z \mid x)</tex> for which <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">I(X;Y) \geq I(X;Z)</tex> holds for all Input distributions. The capacity region for this class of channels resembles the capacity region for degraded message sets considered by Körner and Marton.
