The Design and Analysis of Reliable Communication Networks
In this study, a communication network is represented by a graph, and the problem of designing a network that will operate as reliably as possible is investigated. Failure of the network is associated with the removal of a set of nodes which disconnects the graph or by the removal of a set of edges …

Some Information Theoretic Aspects of Reliable Communication With Transmitter Side Information
For the optimality of the separation architecture, we consider the problem of determining the capacity region of the multiple-input-multiple-output (MIMO) Gaussian broadcast channel. Our main result is a new extremal inequality as the underpinning mathematical structure for the MIMO Gaussian …
