A Survey on Programmable LDPC Decoders

IEEE Access, 2016
Low-density parity-check (LDPC) block codes are popular forward error correction schemes due to their capacity-approaching characteristics. However, the realization of LDPC decoders that meet both low latency and high throughput is not a trivial challenge.

Design of rate-compatible low-density parity-check codes for type-II hybrid ARQ systems

Tongxin xuebao, 2006
The design of powerful rate-compatible low-density parity-check codes（RC-LDPC）was constructed in zigzag structure for type-II hybrid ARQ systems.The generalized PEG algorithm was used in the process of constructing RC-LDPC codes to improve the ...

Jointed LDPC codes design for half-duplex relay channels

Tongxin xuebao, 2013
In order to increase the coding gain of decode-and-forward half-duplex relay channel, a jointed LDPC coding structure and its corresponding optimization scheme was proposed. Novel structure made the subcodes of both source and relay nodes as parts of the

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

ICT 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.

LDPC DropConnect

, 2023
Machine learning is a popular topic that has become a scientific research tool in many fields. Overfitting is a common challenge in machine learning, where the model fits the training data too well and performs poorly on new data. Stochastic regularization is one method used to prevent overfitting, by artificially constraining the model to be simpler ...

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

IEEE 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 $p \equiv 1 (\mathrm {mod} 69)$ .

Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization

EURASIP Journal on Wireless Communications and Networking, 2008
This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC) codes, especially in the context of noncoherent detection.
