Tree-Based Construction of LDPC Codes Having Good Pseudocodeword Weights [PDF]
, 2005 We present a tree-based construction of LDPC codes that have minimum pseudocodeword weight equal to or almost equal to the minimum distance, and perform well with iterative decoding.

An optimized initialization for LDPC decoding over GF(q) in impulsive noise environments.
PLoS ONE, 2021 Modern navigation satellite communication has the characteristic of high transmitting rate. To avoid bit errors in data transmission, low density parity check (LDPC) codes are widely recognized as efficient ways for navigation communication ...

A Nonbinary LDPC-Coded Probabilistic Shaping Scheme for a Rayleigh Fading Channel
Entropy, 2022 In this paper, a novel, nonbinary (NB) LDPC-coded probabilistic shaping (PS) scheme for a Rayleigh fading channel is proposed. For the NB LDPC-coded PS scheme in Rayleigh fading channel, the rotation angle of 16 quadrature amplitude modulation (QAM ...

LDPC Codes Achieve List Decoding Capacity [PDF]
IEEE Annual Symposium on Foundations of Computer Science, 2019 We show that Gallager's ensemble of Low-Density Parity Check (LDPC) codes achieves list-decoding capacity with high probability. These are the first graph-based codes shown to have this property.

Survey of Turbo, LDPC, and Polar Decoder ASIC Implementations
IEEE Communications Surveys and Tutorials, 2019 Channel coding may be viewed as the best-informed and most potent component of cellular communication systems, which is used for correcting the transmission errors inflicted by noise, interference, and fading.

3D EXIT Charts for Analyzing the 5G 3GPP New Radio LDPC Decoder
IEEE Access, 2020 Low Density Parity Check (LDPC) codes have been selected to provide channel coding for data in the next generation of wireless communication standard referred to in practice as the 3GPP New Radio (NR).

Entropy, 2023 In this article, a graph-theoretic method (taking advantage of constraints among sets associated with the corresponding parity-check matrices) is applied for the construction of a double low-density parity-check (D-LDPC) code (also known as LDPC code ...

Optimizing quasi-cyclic spatially coupled LDPC codes by eliminating harmful objects
EURASIP Journal on Wireless Communications and Networking, 2023 It is well known that some harmful objects in the Tanner graph of low-density parity-check (LDPC) codes have a negative impact on their error correction performance under iterative message-passing decoding.
