2014 Poster Sessions : Capacity Region of the Broadcast Channel with Two Deterministic Channel State Components

Student Name : Hyeji Kim
Advisor : Abbas El Gamal
Research Areas: Information Systems
We establish the capacity region of a class of broadcast channels with random state in which each channel component is selected from two possible functions and each receiver knows its state sequence. This channel model does not fit into any class of broadcast channels for which the capacity region was previously known and is useful in studying wireless communication channels when the fading state is known only at the receivers. The capacity region is shown to coincide with the UV outer bound and is achieved via Marton coding.

Hyeji Kim is a PhD candidate at Stanford University. She received her B.S. degree in Electrical Engineering from KAIST in 2011 and M.S. degree in Electrical Engineering from Stanford University in 2013. She is currently working on information theory under supervision of Prof. Abbas El Gamal. Her research interest includes network information theory, statistical learning, and application of information theory and statistics to other disciplines.
