三亚国际数学论坛 Mathematical Theory Applied Coding Cryptography
2017/11/24
Coding and cryptography are an essential subjects in the fields of information security and communication, and they have been applied widely in information technology for several decades of years. Cod...
Coding for Network Coding
Sparse graph codes probabilistic channel models Shannon channel capacity network coding
2015/8/20
We consider communication over a noisy network under randomized linear network coding. Possible error mechanism include node- or link- failures, Byzantine behavior of nodes, or an over-estimate of the...
In this paper we discuss a novel framework for multiclass learning, defined by a suitable coding/decoding strategy, namely the simplex coding, that allows to generalize to multiple classes a relaxatio...

Abstract: Randomized techniques play a fundamental role in theoretical computer science and discrete mathematics, in particular for the design of efficient algorithms and construction of combinatorial...
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...
SNEED: Enhancing Network Security Services Using Network Coding and Joint Capacity
Network Security Services Network Coding Joint Capacity
2011/3/3
Traditional network security protocols depend mainly on developing cryptographic schemes and on using biometric methods. These have led to several network security protocols that are unbreakable based...

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...

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

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...
