Construction of Parallel RIO Codes using Coset Coding with Hamming Codes [PDF]
, 2017 Random input/output (RIO) code is a coding scheme that enables reading of one logical page using a single read threshold in multilevel flash memory. The construction of RIO codes is equivalent to the construction of WOM codes. Parallel RIO (P-RIO) code is an RIO code that encodes all pages in parallel.

CONSTRUCTION OF SHORT-LENGTH HIGH-RATES LDPC CODES USING DIFFERENCE FAMILIES [PDF]
, 2010 Low-density parity-check (LDPC) code is linear-block error-correcting code defined by sparse parity-check matrix. It isdecoded using the massage-passing algorithm, and in many cases, capable of outperforming turbo code.

Reversible Low-Density Parity-Check Codes
IEEE Transactions on Information Theory, 2009 Low-density parity-check (LDPC) codes may be decoded using a circuit implementation of the sum-product algorithm which maps the factor graph of the code. By reusing the decoder for encoding, both tasks can be performed using the same circuit, thus reducing area and verification requirements.

Multiedge-type low-density parity-check codes for continuous-variable quantum key distribution [PDF]
Physical Review A, 2018 Continuous-variable quantum key distribution utilizes an ensemble of coherent states of light to distribute secret encryption keys between two parties. One of the challenges is thereby the requirement of capacity approaching error correcting codes in the

Subsystem Codes with High Thresholds by Gauge Fixing and Reduced Qubit Overhead
Physical Review X, 2021 We introduce a technique that uses gauge fixing to significantly improve the quantum-error-correcting performance of subsystem codes. By changing the order in which check operators are measured, valuable additional information can be gained, and we ...

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.

Low-density parity-check code constructions for hardware implementation
IEEE International Conference on Communications, 2004 We present several hardware architectures to implement low-density parity-check (LDPC) decoders for codes constructed with a hierarchical structure. The proposed hierarchical formulation of the LDPC code allows a structured hardware realization of the ...

Multilevel generalised low-density parity-check codes [PDF]
Electronics Letters, 2006 Multilevel coding invoking generalised low-density parity-check component codes is proposed, which is capable of outperforming the classic low-density parity check component codes at a reduced decoding latency.
