LDPC Error Floor Improvement [PDF]
Engineering and Technology Journal, 2012 The error-correcting performance of low-density parity check (LDPC) codes, when decoded using practical iterative decoding algorithms, is known to be close to Shannon limits.

Array Convolutional Low-Density Parity-Check Codes
, 2013 This paper presents a design technique for obtaining regular time-invariant low-density parity-check convolutional (RTI-LDPCC) codes with low complexity and good performance. We start from previous approaches which unwrap a low-density parity-check (LDPC)

Quasi-Cyclic LDPC Codes based on Pre-Lifted Protographs
, 2014 Quasi-cyclic low-density parity-check (QC-LDPC) codes based on protographs are of great interest to code designers because analysis and implementation are facilitated by the protograph structure and the use of circulant permutation matrices for ...

Effective identification of dominant fully absorbing sets for Raptor-like LDPC codes
ETRI Journal, 2023 The error-rate floor of low-density parity-check (LDPC) codes is attributed to the trapping sets of their Tanner graphs. Among them, fully absorbing sets dominantly affect the error-rate performance, especially for short blocklengths.

Performance Analysis and Design of Two Edge Type LDPC Codes for the BEC Wiretap Channel
, 2011 We consider transmission over a wiretap channel where both the main channel and the wiretapper's channel are Binary Erasure Channels (BEC). We propose a code construction method using two edge type LDPC codes based on the coset encoding scheme.
