A Decoding Algorithm for LDPC Codes Over Erasure Channels with Sporadic Errors [PDF]

open access: yes, 2010
An efficient decoding algorithm for low-density parity-check (LDPC) codes on erasure channels with sporadic errors (i.e., binary error-and-erasure channels with error probability much smaller than the erasure probability) is proposed and its performance ...

Double-Layer Low-Density Parity-Check Codes over Multiple-Input Multiple-Output Channels

open access: yesInternational Journal of Antennas and Propagation, 2012
We introduce a double-layer code based on the combination of a low-density parity-check (LDPC) code with the multiple-input multiple-output (MIMO) system, where the decoding can be done in both inner-iteration and outer-iteration manners.

Efficient Design of Read Voltages and LDPC Codes in NAND Flash Memory Using Density Evolution

open access: yesIEEE Access, 2023
Low-density parity-check (LDPC) codes play an important role in the reliability enhancement of commercial NAND flash memory. Unfortunately, due to the requirement of the reading speed of NAND flash memory, the LDPC decoder will not obtain precise soft ...

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

open access: yes, 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

Research on LDPC Coding for Free Space Optical Communication with Modified Bessel-Gaussian Beams Based on K-distribution

open access: yesMATEC Web of Conferences, 2018
We investigate the performance of low-density parity-check (LDPC) coding for free space optical communication (FSO) with modified Bessel-Gaussian (MBG) beams based on K-distribution.

Research on unequal error protection of irregular LDPC codes

open access: yesTongxin xuebao, 2005
An irregular low-density parity-check (LDPC) code with unequal error protection (UEP) property was proposed. A weight-increasing parity-check (WIPC) matrix was constructed.

Low-Floor Tanner Codes via Hamming-Node or RSCC-Node Doping [PDF]

open access: yes, 2006
We study the design of structured Tanner codes with low error-rate floors on the AWGN channel. The design technique involves the “doping” of standard LDPC (proto-)graphs, by which we mean Hamming or recursive systematic convolutional (RSC) code ...

The Analytical Description of Regular LDPC Codes Correcting Ability

open access: yesTransport and Telecommunication, 2014
The analytical description of regular LDPC (Low-Density Parity Check) codes correcting ability has been investigated. The statistical dependencies for the maximum number of corrected bits per the code word as a function of LDPC code word length and code ...

COMPARATIVE ANALYSIS OF LDPC AND BCH CODES ERROR-CORRECTING CAPABILITIES

open access: yesInformation and Telecommunication Sciences, 2014
The error-correcting capabilities of regular LDPC (Low Density Parity Check) codes and BCH (Bose-Chaudhuri-Hocquenguem) codes are examined. The qualitative analysis and the quantitative assessment of error-correcting abilities are performed for LDPC ...
