Design of LDPC Codes: A Survey and New Results
Journal of Communications Software and Systems, 2006 This survey paper provides fundamentals in the design of LDPC codes. To provide a target for the code designer, we first summarize the EXIT chart technique for determining(near-)optimal degree distributions for LDPC code ensembles.

Evaluation of Low Density Parity Check Codes Over Various Channel Types [PDF]
Engineering and Technology Journal, 2011 Low density parity check (LDPC) codes are one of the best error correcting codes in today’s coding world and are known to approach the Shannon limit. As with all other channel coding schemes, LDPC codes add redundancy to the uncoded input data to make it

New Technique for Improving Performance of LDPC Codes in the Presence of Trapping Sets
EURASIP Journal on Wireless Communications and Networking, 2008 Trapping sets are considered the primary factor for degrading the performance of low-density parity-check (LDPC) codes in the error-floor region. The effect of trapping sets on the performance of an LDPC code becomes worse as the code size decreases. One

High performance short-block binary regular LDPC codes
Alexandria Engineering Journal, 2018 LDPC code shows a good performance with long-block codes. However, certain channels are constrained to use short-block codes due to latency. Therefore, concatenated LDPC codes with iterative decoding is a good choice to get a good performance ...

Deriving Good LDPC Convolutional Codes from LDPC Block Codes [PDF]
IEEE Transactions on Information Theory, 2011 Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent performance with low encoding and decoding complexity. In this paper we discuss several graph-cover-based methods for deriving families of time-invariant and time-varying LDPC convolutional codes from LDPC block codes and show how earlier proposed LDPC convolutional ...

Reverse Concatenated Coded Modulation for High-Speed Optical Communication
IEEE Photonics Journal, 2010 We propose the reverse concatenated code as a forward error correction (FEC) scheme suitable for beyond 100-Gb/s optical transmission. In this scheme, BCH code is used as inner code and low-density parity-check (LDPC) code as outer code.

Implementation of Decoders for LDPC Block Codes and LDPC Convolutional Codes Based on GPUs [PDF]
IEEE Transactions on Parallel and Distributed Systems, 2014 With the use of belief propagation (BP) decoding algorithm, low-density parity-check (LDPC) codes can achieve near-Shannon limit performance. In order to evaluate the error performance of LDPC codes, simulators running on CPUs are commonly used. However, the time taken to evaluate LDPC codes with very good error performance is excessive. In this paper,

On Sparse Regression LDPC Codes
2023 IEEE International Symposium on Information Theory (ISIT), 2023 Belief propagation applied to iterative decoding and sparse recovery through approximate message passing (AMP) are two research areas that have seen monumental progress in recent decades. Inspired by these advances, this article introduces sparse regression LDPC codes and their decoding.
