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.

Derived dynamic scheduling for belief propagation decoding of LDPC codes

Electronics Letters
Among numerous dynamic scheduling strategies for low‐density parity‐check codes, many of them are of high complexity due to repetitive computation and ordering of belief residuals.

Finite Length Analysis of Low-Density Parity-Check Codes on Impulsive Noise Channels

IEEE Access, 2016
Low-density parity-check (LDPC) codes with very long block lengths are well known for their powerful error correction, but it is not always desirable to employ long codes in communication systems, where latency is a serious issue, such as voice and video

Double-Layer Low-Density Parity-Check Codes over Multiple-Input Multiple-Output Channels

International Journal of Antennas and Propagation, 2012
We introduce a double-layer code based on the combination of a low-density parity-check (LDPC) code with the multiple-input multiple-output (MIMO) system, where the decoding can be done in both inner-iteration and outer-iteration manners.

Toward a 2D Local Implementation of Quantum Low-Density Parity-Check Codes

PRX Quantum
Geometric locality is an important theoretical and practical factor for quantum low-density parity-check (qLDPC) codes that affects code performance and ease of physical realization. For device architectures restricted to two-dimensional (2D) local gates,

Nonlocal resources for error correction in quantum low-density parity-check codes

Physical Review Research
Quantum low-density parity-check (qLDPC) codes with high-performance and nonlocal stabilizers are an attractive alternative to the surface code because of their relatively high code rate and distance.

Generalized low-density parity-check codes

, 2006
An evolution of Gallager's Low-Density Parity-Check (LDPC) codes was first introduced by Tanner in 1981, namely Generalized Low-Density Parity-Check (GLDPC) codes, and then further developed by Boutros et at. as well as by Lentmaier and Zigangirov. It has been shown that Hamming-code based GLDPC codes are asymptotically good in the sense of minimum ...

Research on unequal error protection of irregular LDPC codes

Tongxin xuebao, 2005
An irregular low-density parity-check （LDPC） code with unequal error protection （UEP） property was proposed. A weight-increasing parity-check （WIPC） matrix was constructed.
