Dependence Balance and Capacity Bounds for Multiterminal Communication and Wiretap Channels
Amin Gohari, Gerhard Kramer
An information measure based on fractional partitions of a set is used to derive a general dependence balance inequality for communication. This inequality is used to obtain new up…
The capacity region of classes of product broadcast channels
Yanlin Geng, Amin Gohari, Chandra Nair +1
We establish a new outer bound for the capacity region of product broadcast channels. This outer bound matches Marton's inner bound for a variety of classes of product broadcast ch…
Source Coding with Free Bits and the Multi-Way Number Partitioning Problem
Niloufar Ahmadypour, Amin Gohari
We introduce a new variant of variable-length source coding for sending a source over two parallel channels, one of which is costly and the other free. We give a complete solution…
On the Ratio of Shannon Numbers of Graphs
Sharareh Alipour, Amin Gohari, Mehrshad Taziki
Let be a function that maps two arbitrary graphs and to a non-negative real number such that where is any…
