Non-equilibrium Information Envelopes and the Capacity-Delay-Error-Tradeoff of Source Coding
Non-equilibrium Information Envelopes Capacity-Delay-Error-Tradeoff Source Coding Information Theory
2011/10/8
Abstract: This paper develops an envelope-based approach to establish a link between information and queueing theory. Unlike classical, equilibrium information theory, information envelopes focus on t...
Linear Index Coding via Semidefinite Programming
Linear Index Coding Semidefinite Programming Data Structures and Algorithms
2011/9/30
Abstract: In the index coding problem, introduced by Birk and Kol (INFOCOM, 1998), the goal is to broadcast an n bit word to n receivers (one bit per receiver), where the receivers have side informati...
Interference Networks with General Message Sets: A Random Coding Scheme
Interference Networks General Message Sets Broadcast Channel Mutiple Access Channel
2011/8/31
Abstract: In this paper, the Interference Network with General Message Sets (IN-GMS) is introduced in which several transmitters send messages to several receivers: Each subset of transmitters transmi...
Abstract: The last decades have seen a growing interest in hash functions that allow some sort of tolerance, e.g. for the purpose of biometric authentication. Among these, the syndrome fuzzy hashing c...
Abstract: A sender wishes to broadcast an n character word x in F^n (for a field F) to n receivers R_1,...,R_n. Every receiver has some side information on x consisting of a subset of the characters o...

On Transmit Antenna Selection for Multiuser MIMO Systems with Dirty Paper Coding
Transmit Antenna Selection Multiuser MIMO Systems Dirty Paper Coding
2011/1/19
Abstract—In this paper, we address the transmit antenna selection in multi-user MIMO systems with precoding. The optimum and reduced complexity sub-optimum antenna selection algorithms are introduced.
Coding for High-Density Recording on a 1-D Granular Magnetic Medium
High-Density Recording 1-D Granular Magnetic Medium
2011/1/19
In terabit-density magnetic recording, several bits of data can be replaced by the values of their neighbors in the storage medium. As a result, errors in the medium are dependent on each other and al...
Noisy channel coding via privacy amplification and information reconciliation
Noisy channel coding privacy amplification information reconciliation
2011/3/3
We show that optimal protocols for noisy channel coding of public or private information over either classical or quantum channels can be directly constructed from two more primitive information-theor...
Constructing Quantum Network Coding Schemes from Classical Nonlinear Protocols

2011/3/3
The k-pair problem in network coding theory asks to send k messages simultaneously between k
source-target pairs over a directed acyclic graph. In a previous paper [ICALP 2009, Part I, pages 622–633]...
The penalty incurred by imposing a finite delay constraint in lossless source coding of a memoryless source is investigated.
This paper investigates universal polar coding schemes. In particular, a notion of ordering (called convolutional path) is introduced between probability distributions to determine when a polar compre...
A New Noncoherent Decoder for Wireless Network Coding
New Noncoherent Decoder Wireless Network Coding
2011/3/1
This work deals with the decoding aspect of wireless network coding in the canonical two-way relay channel where two senders exchange messages via a common relay and they receive the mixture of two me...
Wavelet image coding measurement based on system visual human
DWT copression image quality
2010/9/27
A reliable quality measurement is a much needed tool for determining the type and amount of image distortion for the embedded zero tree wavelet image coding based on perceptual techniques. Attempts to...
An Infinite Surface With The Lattice Property I: Veech Groups and Coding Geodesics
The Lattice Property I Veech Groups Coding Geodesics
2010/11/9
We study the symmetries and geodesics of an infinite translation surface which arises as a limit of translation surfaces built from regular polygons, studied by Veech. We find the affine symmetry grou...
