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.

On the Stopping Distance of SA-LDPC Codes by Transversal Designs

IEEE Access, 2018
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 ...

Tanner $(J,L)$ Quasi-Cyclic LDPC Codes: Girth Analysis and Derived Codes

IEEE Access, 2019
Girth plays an important role in the design of low-density parity-check (LDPC) codes. Motivated by the works on the girth of some classes of Tanner quasi-cyclic (QC) LDPC codes, e.g., Tanner (3, 5), (3, 7), (3, 11), and (5, 7) codes, we, in this paper ...

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.

ANALYSIS OF CORRECTIVE PROPERTIES OF ULTRA-LONG LDPC CODES

Information and Telecommunication Sciences, 2013
The ultra-long LPDC codes are examined. The errors correction by ultra-long LDPC codes is analyzed. The error-correcting capability research method for ultra-long LDPC codes is described in details. The main results in table and graph representations are

From Product Codes to Structured Generalized LDPC Codes

, 2010
Product codes, due to their relatively large minimum distance, are often seen as a natural solution for applications requiring low error floors.

Low latency low power bit flipping algorithms for LDPC decoding [PDF]

, 2010
Low Density Parity Check (LDPC) codes have been adopted in a number of wired and wireless communication standards due to their improved error correcting ability and relatively simple decoder structure.

Decoder-in-the-Loop: Genetic Optimization-Based LDPC Code Design

IEEE Access, 2019
LDPC code design tools typically rely on asymptotic code behavior and are affected by an unavoidable performance degradation due to model imperfections in the short length regime.
