Learning to Decode Protograph LDPC Codes [PDF]
IEEE Journal on Selected Areas in Communications, 2021 The recent development of deep learning methods provides a new approach to optimize the belief propagation (BP) decoding of linear codes. However, the limitation of existing works is that the scale of neural networks increases rapidly with the codelength,

Toward a Union-Find Decoder for Quantum LDPC Codes [PDF]
IEEE Transactions on Information Theory, 2021 Quantum LDPC codes are a promising direction for low overhead quantum computing. In this paper, we propose a generalization of the Union-Find decoder as a decoder for quantum LDPC codes.

Rate compatible reconciliation for continuous-variable quantum key distribution using Raptor-like LDPC codes [PDF]
Science China Physics Mechanics and Astronomy, 2021 In the practical continuous-variable quantum key distribution (CV-QKD) system, the postprocessing process, particularly the error correction part, significantly impacts the system performance. Multi-edge type low-density parity-check (MET-LDPC) codes are

Quantum LDPC Codes With Almost Linear Minimum Distance [PDF]
IEEE Transactions on Information Theory, 2020 We give a construction of quantum LDPC codes of dimension $\Theta (\log N)$ and distance $\Theta (N/\log N)$ as the code length $N\to \infty $ . Using a product of chain complexes this construction also provides a family of quantum LDPC codes of ...

A Survey on High-Throughput Non-Binary LDPC Decoders: ASIC, FPGA, and GPU Architectures
IEEE Communications Surveys and Tutorials, 2022 Non-binary low-density parity-check (NB-LDPC) codes show higher error-correcting performance than binary low-density parity-check (LDPC) codes when the codeword length is moderate and/or the channel has bursts of errors.

Joint parameter estimation and decoding in a distributed receiver
International Journal of Satellite Communications and Networking, Volume 41, Issue 1, Page 59-81, January/February 2023., 2023 This paper presents an algorithm for iterative joint channel parameter (carrier phase, Doppler shift, and Doppler rate) estimation and decoding of transmission over channels affected by Doppler shift and Doppler rate using a distributed receiver. We derive the Weighted Bayesian Cramer‐Rao Bounds for joint carrier phase, Doppler shift, and Doppler rate ...
