Reliability Ratio Based Weighted Bit-Flipping Decoding for LDPC Codes

open access: yes, 2005
In this contribution, a novel reliability-ratio based weighted bit-flipping(RRWBF) algorithm is proposed for decoding Low Density Parity Check (LDPC) codes.

Design of LDPC code for uncorrelated Rayleigh fading channel using modified outage probability

open access: yesICT Express
In this paper, we propose a new design metric called modified outage probability (MOP) for protograph-based low-density parity-check (LDPC) codes over the uncorrelated Rayleigh fading channel.

Multilevel structured low-density parity-check codes for AWGN and Rayleigh channels

open access: yes, 2010
We propose a novel class of protograph low-density parity-check (LDPC) codes having a combinatorial rather than a random structure, which are termed multilevel-structured (MLS) LDPC codes. It is demonstrated that they posses a strikingly simple structure

Tanner (3, 23)-Regular QC-LDPC Codes: Cycle Structure and Girth Distribution

open access: yesIEEE Access
This paper studies a class of quasi-cyclic LDPC (QC-LDPC) codes, i.e., Tanner (3, 23)-regular QC-LDPC codes of code length $23p$ with $p$ being a prime and $p \equiv 1 (\mathrm {mod} 69)$ .

Low-Complexity Non-Binary LDPC and Modulation Schemes communicating over MIMO Channels

open access: yes, 2004
In this contribution, Pearl’s belief propagation (BP) algorithm is invoked for constructing a belief network, which is employed for developing a joint detection aided transmit diversity scheme and a non-binary LDPC decoder constructed over a finite field

Analysis of LDPC convolutional codes derived from LDPC block codes

open access: yes, 2008
LDPC convolutional codes have been shown to be capable of achieving the same capacity-approaching performance as LDPC block codes with iterative message passing decoding.

Nonbinary Hybrid LDPC Codes

open access: yes, 2010
International audienceIn this paper, a new class of low-density parity-check (LDPC) codes, named hybrid LDPC codes, is introduced. Hybrid LDPC codes are characterized by an irregular connectivity profile and heterogeneous orders of the symbols in the ...

Generalized Low-Density Parity-Check Coding Aided Multilevel Codes

open access: yes, 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.
