A Combined Matrix Ensemble of Low-Density Parity-Check Codes for Correcting a Solid Burst Erasure
A new ensemble of low-density parity-check (LDPC) codes for correcting a solid burst erasure is proposed. This ensemble is an instance of a combined matrix ensemble obtained by concatenating some LDPC matrices. We derive a new bound on the critical minimum span ratio of stopping sets for the proposed code ensemble by modifying the bound for ordinary code ensemble. By calculating this bound, we ...
متن کاملPerformance of Low-Density Parity-Check Codes for Burst Erasure Channels
Performance of low-density parity-check (LDPC) codes with maximum likelihood decoding (MLD) for solid burst erasures is discussed. The columns of the paritycheck matrix of LDPC codes are permuted to increase the distance between elements (DBEs) which are defined as a number of symbol positions between elements 1 at each row of the parity-check matrix. The column permutation method can change th...

BURST CORRECTION CODING FROM LOW-DENSITY PARITY-CHECK CODES Wai Han Fong, PhD George Mason University, 2015 Dissertation Director: Dr. Shih-Chun Chang Dissertation Co-Director: Dr. Shu Lin This thesis explores techniques and theoretical bounds on efficiently encodable low-density parity-check (LDPC) codes for correcting single and multiple bursts of erasures and/or errors. The approach is to co...
متن کاملLow Density Parity Check Codes
Low Density Parity Check Codes originally invented by Gallagher and subsequently rediscovered by multiple groups 30 years later has become the best known error correcting code in a variety of situations. In this paper, we review regular and irregular LDPC codes. We describe a number of message passing decoders for decoding these codes and explain their operation via examples. Density evolution,...
متن کاملLow-density parity-check codes
A low-density parity-check code is a code specified by a parity-check matrix with the following properties : each column contains a small fixed numberj > 3 of I’s and each row contains a small fixed number k > j of 1’s. The typical minimum distance of these codes increases linearly with block length for a fixed rate and fixed j. When used with maximum likelihood decoding on a snfhciently quiet ...
