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.

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 ...

Quasi-cyclic multi-edge LDPC codes for long-distance quantum cryptography [PDF]
npj Quantum Information, 2017 The speed at which two remote parties can exchange secret keys in continuous-variable quantum key distribution (CV-QKD) is currently limited by the computational complexity of key reconciliation.

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 ...

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.

Protograph-Based LDPC Code Design for Shaped Bit-Metric Decoding [PDF]
, 2015 A protograph-based low-density parity-check (LDPC) code design technique for bandwidth-efficient coded modulation is presented. The approach jointly optimizes the LDPC code node degrees and the mapping of the coded bits to the bit-interleaved coded ...

Improving soft FEC performance for higher-order modulations via optimized bit channel mappings [PDF]
, 2014 Soft forward error correction with higher-order modulations is often implemented in practice via the pragmatic bit-interleaved coded modulation paradigm, where a single binary code is mapped to a nonbinary modulation.
