LDPC Code Design for Nonuniform Power-Line Channels
We investigate low-density parity-check code design for discrete multitone channels over power lines. Discrete multitone channels are well modeled as nonuniform channels, that is, different bits experience various channel parameters.

On the Stopping Distance of SA-LDPC Codes by Transversal Designs
In this paper, we analyze the size of the smallest stopping set (called the stopping distance) for the parity-check matrix of a superposed array low-density parity-check (SA-LDPC) code for column weights 3 and 4 by using the transversal design (TD ...

Simple reconfigurable low-density parity-check codes [PDF]
Low-density parity-check codes (LDPCC) have been recently investigated as a possible solution for high data rate applications, for both space and terrestrial wireless communications. A main issue is the research of low complexity encoding and decoding schemes.

Low-Density Parity-Check Codes and Their Rateless Relatives [PDF]
This survey guides the reader through the extensive open literature that is covering the family of low-density parity-check LDPC codes and their rateless relatives. In doing so, we will identify the most important milestones that have occurred since their conception until the current era and elucidate the related design problems and their respective ...

Evaluation of Low Density Parity Check Codes Over Various Channel Types [PDF]
Low density parity check (LDPC) codes are one of the best error correcting codes in today’s coding world and are known to approach the Shannon limit. As with all other channel coding schemes, LDPC codes add redundancy to the uncoded input data to make it

Interactive reconciliation with low-density parity-check codes [PDF]
Efficient information reconciliation is crucial in several scenarios, being quantum key distribution a remarkable example. However, efficiency is not the only requirement for determining the quality of the information reconciliation process. In some of these scenarios we find other relevant parameters such as the interactivity or the adaptability to ...

Error-correction on non-standard communication channels [PDF]
Many communication systems are poorly modelled by the standard channels assumed in the information theory literature, such as the binary symmetric channel or the additive white Gaussian noise channel.

Spatially Coupled Generalized Low-Density Parity-Check Codes Over Class-A Impulsive Noise Channels
In this paper, a class of spatially coupled generalized low-density parity-check (SC-GLDPC) codes with minimum coupling width is introduced to mitigate the Class-A impulsive noise. Codes with minimum coupling width are beneficial to simple code structure,

Low-Density Parity-Check Codes
Low-density parity-check (LDPC) error correcting codes were introduced in 1963 by Robert Gallager in his Ph.D. thesis. The basic motivation came from the observation that random linear codes, cf.

On the capacity of low-density parity-check codes [PDF]
We demonstrate that we can translate threshold values of low-density parity-check (LDPC) codes between channels accurately using a simple mapping. We develop some models of density evolution from this observation, namely erasure-channel and reciprocal-channel approximations.
