On the Structure of the Capacity Region of Asynchronous Memoryless Multiple-Access Channels

Bixio Rimoldi, Ninoslav Marina

The asynchronous capacity region of memoryless multiple-access channels is the union of certain polytopes. It is well-known that vertices of such polytopes may be ap- proached via a technique called successive decoding. It is also known that an extension o ...

Dense Disparity Estimation in a Multi-view Distributed Video Coding System

Thomas Maugey

Distributed video coding (DVC) is a recent paradigm which aims at transferring part of the coding complexity from the encoder to the decoder. The performance of such a coding scheme strongly depends on the capacity to estimate correlation at the decoder an ...

Code Construction for Multiple Sources Network Coding

Christina Fragouli, Suhas Diggavi

In several wireless applications multiple sources transmit information to one or more receivers, many times over unknown topologies. This is especially so in mobile networks where learning the topology may have prohibitive complexity. Network coding techni ...

Multiple Description Coding for Stationary Gaussian Sources

Suhas Diggavi, Jun Chen

We consider the problem of multiple description coding for stationary Gaussian sources under the squared error distortion measure. The rate region is characterized for the 2-description case. It is shown that each supporting line of the rate region is achi ...

Invertible Extractors and Wiretap Protocols

Mohammad Amin Shokrollahi, Mahdi Cheraghchi Bashi Astaneh

A wiretap protocol is a pair of randomized encoding and decoding functions such that knowledge of a bounded fraction of the encoding of a message reveals essentially no information about the message, while knowledge of the entire encoding reveals the messa ...

DISTRIBUTED VIDEO CODING: TRENDS AND PERSPECTIVES

Frédéric Dufaux, Wen Gao

This paper surveys recent trends and perspectives in distributed video coding. More specifically, issues such as coding efficiency, error resilience, multi-view coding, scalability, and applications beyond coding are overviewed. In addition, recent contrib ...

Non-binary LDPC codes and EXIT like functions

In the first part of this thesis we are interested in the asymptotic performance analysis of Non-Binary Low-Density Parity-Check (NBLDPC) codes over the Binary Erasure Channel (BEC) decoded via the suboptimal Belief Propagation (BP) decoder as well as the ...

On the Minimum Distance of Non Binary LDPC Codes

Rethnakaran Pulikkoonattu

Minimum distance is an important parameter of a linear error correcting code. For improved performance of binary Low Density Parity Check (LDPC) codes, we need to have the minimum distance grow fast with n, the codelength. However, the best we can hope for ...

Concentration of Magnetization for Linear Block Codes

Nicolas Macris, Satish Babu Korada, Shrinivas Kudekar

We consider communication over the binary erasure and the binary additive white gaussian noise channels using fixed linear block codes and also appropriate ensembles of such codes. We show concentration of the magnetization over the channel realizations an ...

Decay of Correlations: An Application to Low-Density Parity Check codes

Nicolas Macris, Shrinivas Kudekar

Recently the decay of correlations between bits of low density generator matrix (LDGM) codes have been investigated by using high temperature expansions from statistical physics \cite{KuMa07}. In this work we apply these ideas to a special class of low den ...
