"Graph Entropy, Network Coding and Guessing games" [PDF]

open access: yes, 2007
We introduce the (private) entropy of a directed graph (in a new network coding sense) as well as a number of related concepts. We show that the entropy of a directed graph is identical to its guessing number and can be bounded from below with the number

On practical design for joint distributed source and network coding [PDF]

open access: yes, 2009
This paper considers the problem of communicating correlated information from multiple source nodes over a network of noiseless channels to multiple destination nodes, where each destination node wants to recover all sources. The problem involves a joint

Distributed Source-coding, Channel-coding and Modulation for Cooperative Communications [PDF]

open access: yes, 2010
In this contribution, we propose a novel Distributed Source-coding, Channel-coding and Modulation (DSCM) scheme for cooperative communications. The proposed DSCM scheme is designed for ensuring the decoding convergence of its constituent component codes,

Unveiling Near-Capacity Code Design: The Realization of Shannon's Communication Theory for MIMO Channels [PDF]

open access: yes, 2008
In this contribution we show how Shannon’s coding theory could be realized for Multiple-Input Multiple-Output (MIMO) channels with the aid of EXtrinsic Information Transfer (EXIT) charts and the Maximum-Aposteriori Probability (MAP) algorithm.

Network Coding and Distributed Compression over Large Networks: Some Basic Principles [PDF]

open access: yes, 2012
The fields of Network Coding and Distributed Compression have focused primarily on finding the capacity for families of problems defined by either a broad class of networks topologies (e.g., directed, acyclic networks) under a narrow class of demands (e ...
