Delay with network coding and feedback

Christina Fragouli, Lorenzo Keller

We consider the problem of minimizing delay when broadcasting over erasure channels with feedback. A sender wishes to communicate the same set of μ messages to several receivers over separate erasure channels. The sender can broad- cast a single message or ...

Towards Global Bilevel Dynamic Optimization

Benoît Chachuat

The global solution of bilevel dynamic optimization problems is discussed. An overview of a deterministic algorithm for bilevel programs with nonconvex functions participating is given, followed by a summary of deterministic algorithms for the global solut ...

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 ...

AN OPERATOR FORMULATION OF THE MULTISCALE FINITE-VOLUME METHOD WITH CORRECTION FUNCTION

Ivan Lunati

The multiscale finite-volume (MSFV) method has been derived to efficiently solve large problems with spatially varying coefficients. The fine-scale problem is subdivided into local problems that can be solved separately and are coupled by a global problem. ...

Real-time Delay with Network Coding and Feedback

Christina Fragouli, Lorenzo Keller

We consider the problem of minimizing delay when broadcasting over erasure channels with feedback. A sender wishes to communicate the same set of m messages to several receivers. The sender can broadcast a single message or a combination (encoding) of mess ...

M-DPOP: Faithful distributed implementation of efficient social choice problems

Boi Faltings, Adrian Petcu, David C. Parkes

In the efficient social choice problem, the goal is to assign values, subject to side constraints, to a set of variables to maximize the total utility across a population of agents, where each agent has private information about its utility function. In th ...

A source coding scheme using sparse graphs: Modern Coding Theory Course Exam 2008

Rethnakaran Pulikkoonattu

This is the report that submitted towards the final examination evaluation of the doctoral course \textit{Modern Coding theory} by Ruediger Urbanke at EPFL during Spring 2008. The problem studied can be roughly stated as source coding or compression using ...

Asymmetric multi-level diversity coding

Suhas Diggavi

Symmetric multilevel diversity coding was introduced by Roche et al, where a set of K information sources is encoded by K encoders and the decoders reconstruct sources 1, . . . , k, where k is the number of encoders to which they have access. In this paper ...

Bitstream format for spatio-temporal wave field coder

Martin Vetterli, Francisco Pereira Correia Pinto

We present a non-parametric method for compressing multichannel audio data for reproduction through Wave Field Synthesis. The method consists of applying a two-dimensional filterbank to the input mul- tichannel signal, in both time and channel dimensions, ...
