Distributed QC-LDPC Coded Spatial Modulation for Half-Duplex Wireless Communications [PDF]

Radioengineering, 2022
The bit error rate (BER) performance of spatial modulation (SM) can be further improved by applying quasi-cyclic low-density parity-check (QC-LDPC) codes recommended in 5G to SM.

Analysis of reaction and timing attacks against cryptosystems based on sparse parity-check codes

, 2019
In this paper we study reaction and timing attacks against cryptosystems based on sparse parity-check codes, which encompass low-density parity-check (LDPC) codes and moderate-density parity-check (MDPC) codes.

Array Convolutional Low-Density Parity-Check Codes

, 2013
This paper presents a design technique for obtaining regular time-invariant low-density parity-check convolutional (RTI-LDPCC) codes with low complexity and good performance. We start from previous approaches which unwrap a low-density parity-check (LDPC)

Acceleration of low density parity check code (LDPC) decoding by successive overrelaxations [PDF]

Electronics Letters, 2018
Belief propagation and variants are the usual decoding algorithms for low‐density parity check codes. The successive overrelaxations are applied to increase the convergence speed of the decoding process. Performances are reported and improvements over the reference algorithms are observed.

QMM‐Enhanced Error Correction: Demonstrating Reversible Imprinting and Retrieval for Robust Quantum Computation

Advanced Quantum Technologies, Volume 8, Issue 9, September 2025.
Hardware experiments show a single‐layer Quantum Memory Matrix booster cuts logical error sixfold and, when prepended to a [3,1,3]$[3,1,3]$ repetition code, attains 94 % logical fidelity without extra CX gates. QMM dressing also lowers variational‐training loss by 35 %, offering a measurement‐free, resource‐light route to error suppression on NISQ ...

FPGA implementation of low density parity-check (LDPC) coded recording channels [PDF]

, 2019
Low Density Parity-Check (LDPC) codes have received lots of attention during the past decade due to their near Shannon-limit performance and decoding at very high rates. However, several issues have been raised in the research work with an aim to achieve the practical implementation of the LDPC codes. The first major issue is the performance evaluation
