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...
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...
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
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...

Novel Codes Family Modified Spectral-Amplitude-Coding OCDMA Systems Performance Analysis
2010/12/10
In this paper a novel family of codes for modified spectral-amplitude-coding optical code division multiple access (SAC-OCDMA) is introduced. The proposed codes exist for more number of processing gai...
In [13], K¨otter and Kschischang presented a new model for error correcting codes in network coding. The alphabet in this model is the subspace lattice of a given vector space.

Relay Selection Network Coding Two-Way Relay Channels
2010/12/13
Abstract—In this paper, we consider the design of joint network coding (NC) and relay selection (RS) in two-way relay channels.In the proposed schemes, two users first sequentially broadcast their res...
Morphological dilation image coding with context weights prediction
quad-tree coding morphological dilation variable-length group test coding weights training
2010/12/14
This paper proposes an adaptive morphological dilation image coding with context weights prediction. The new dilation method is not to use fixed models, but to decide whether a coefficient needs to be...

Applications semidefinite programming to coding theory
2010/12/1
We survey recent generalizations and improvements of the linear programming method that involve semidefinite programming. A general framework using group representations and tools from graph theory is...

Bit-Interleaved Coded Multiple Beamforming Perfect Coding
2010/12/8
When the Channel State Information (CSI) is known by the transmitter as well as the receiver, beamforming techniques that employ Singular Value Decomposition (SVD) are commonly used in Multiple-InputM...
