Protograph EXIT Analysis over Block Fading Channels with Application to Relays [PDF]

, 2012
An accurate extrinsic information transfer (EXIT) analysis is developed for protograph low-density parity-check (LDPC) codes over the block fading channel (BFC). The analysis is thus exploited for analyzing the behavior of distributed protograph LDPC

Graph-Based Codes and Iterative Decoding [PDF]

, 2003
The field of error correcting codes was revolutionized by the introduction of turbo codes in 1993. These codes demonstrated dramatic performance improvements over any previously known codes, with significantly lower complexity.

Low-rate coding using incremental redundancy for GLDPC codes [PDF]

, 2008
In this paper we propose a low-rate coding method, suited for application-layer forward error correction. Depending on channel conditions, the coding scheme we propose can switch from a fixed-rate LDPC code to various low-rate GLDPC codes.

Multilevel Generalised Low-Density Parity-Check Codes [PDF]

, 2006
Multilevel coding invoking generalised low-density parity-check component codes is proposed, which is capable of outperforming the classic low-density parity check component codes at a reduced decoding ...

Low-Lee-Density Parity-Check Codes [PDF]

, 2020
We introduce a new family of linear block codes over Zq that we name low-Lee-density parity-check (LLDPC) codes. These codes, which are embedded with the Lee metric, are characterized by a parity-check matrix whose rows and columns have low Lee weight ...

Design of Low-Density Parity-Check Code Pair for Joint Source-Channel Coding Systems Based on Graph Theory

Entropy, 2023
In this article, a graph-theoretic method (taking advantage of constraints among sets associated with the corresponding parity-check matrices) is applied for the construction of a double low-density parity-check (D-LDPC) code (also known as LDPC code ...

Erasure codes with a banded structure for hybrid iterative-ML decoding [PDF]

, 2009
This paper presents new FEC codes for the erasure channel, LDPC-Band, that have been designed so as to optimize a hybrid iterative-Maximum Likelihood (ML) decoding.

Generalized Low-Density Parity-Check Coding Aided Multilevel Codes [PDF]

, 2006
Classic Low-Density Parity-Check (LDPC) codes have recently been used as component codes in Multilevel Coding (MLC) due to their impressive BER performance as well as owing to their flexible coding rates.
