Network Coding With Modular Lattices
Mar 2010
Network coding is a tool for information transmission in networks. A network is considered to be a directed graph, where an edge from a vertex u to a vertex v is drawn, if u is able to send...

Low-Density Graph Codes for Coded Cooperation on Slow Fading Relay Channels
Mar 2011
The authors study Low-Density Parity-Check (LDPC) codes with iterative decoding on Block-Fading (BF) Relay Channels. They consider two users that employ coded cooperation, a variant of...

On the Growth Rate of the Weight Distribution of Irregular Doubly-Generalized LDPC Codes
May 2010
In this paper, an expression for the asymptotic growth rate of the number of small linear-weight codewords of irregular Doubly-Generalized LDPC (D-GLDPC) codes is derived. The expression is...

Large-System Analysis of Multiuser Detection With an Unknown Number of Users: A High-SNR Approach
Oct 2010
The authors analyze multiuser detection under the assumption that the number of users accessing the channel is unknown by the receiver. In this environment, users' activity must be estimated along...

Graph-Theoretical Constructions for Graph Entropy and Network Coding Based Communications
Oct 2010
The guessing number of a directed graph (digraph), equivalent to the entropy of that digraph, was introduced as a direct criterion on the solvability of a network coding instance. This paper makes...
