Rate Regions for Multiple Access Relay Channels with Relay-Source Feedback

Speaker: Jie Hou,
Institute for Communications Engineering,
Technical University of MunichAbstract: For the multiple-access relay channel with relay-source feedback,
we derive an outer bound on the capacity region. We also derive an
achievable rate region which is in general larger than the capacity region
without feedback. The presence of the
feedback enables the sources to understand each other¹s messages, which in
turn allows the sources to cooperate to resolve the residual uncertainty at
the receiver in an efficient way. At the same time, independent fresh
information from the sources is superimposed upon the resolution
information.Biography: Jie Hou received the Dipl.-Ing. degree in electrical engineering
from the Technical University of Munich in 2008. He is currently working
towards his Ph.D. degree at the Institute for Communications Engineering at
the Technical University of Munich. His research interests are multiuser
information theory and practical code design.Host: Prof. Gerhard Kramer,gkramer@usc.edu
