Low density parity check coding. [PDF]
IEEE Communications Letters, 2005 This thesis explores the properties of the family of Low Density Parity Check Codes (LDPCC). In addition to Gallager's original binary regular LDPCCs, the class of irregular LDPCCs and non-binary LDPCCs developed from the binary regular LDPCC is also studied.

Multilevel Structured Low-Density Parity-Check Codes [PDF]
2008 IEEE International Conference on Communications, 2008 Low-density parity-check (LDPC) codes are typically characterized by a relatively high-complexity description, since a considerable amount of memory is required in order to store their code description, which can be represented either by the connections of the edges in their Tanner graph or by the non-zero entries in their parity-check matrix (PCM ...

Doped low-density parity-check codes
Digital Communications and NetworksIn this paper, we propose a doping approach to lower the error floor of Low-Density Parity-Check (LDPC) codes. The doping component is a short block code in which the information bits are selected from the coded bits of the dominant trapping sets of the ...

On Girth Conditioning for Low-Density Parity-Check Codes [PDF]
IEEE Transactions on Communications, 2011 Low-density parity-check (LDPC) codes are gaining interest for high data rate applications in both terrestrial and spatial communications. They can be designed and studied through a bipartite graph whose characteristics affect the performance. This paper proposes a low-complexity method to improve the performance of LDPC codes by selectively removing ...

Single and joint iterative decoding for higher order modulation schemes [PDF]
, 2008 The research project described in this thesis concentrates on the study, and application of specific channel coding techniques, in particular, low-density parity-check (LDPC) codes, iterative decoding on Tanner graphs, and their application on joint ...

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.

Fifteen Years of Quantum LDPC Coding and Improved Decoding Strategies
IEEE Access, 2015 The near-capacity performance of classical low-density parity check (LDPC) codes and their efficient iterative decoding makes quantum LDPC (QLPDC) codes a promising candidate for quantum error correction.

Amalgamated Generalized Low Density Parity Check and Luby Transform Codes for the Wireless Internet [PDF]
, 2007 Luby Transform codes (LT) were originally designed for the Binary Erasure Channel (BEC) encountered owing to randomly dropped packets in the statistical multiplexing aided Internet, where transmitted packets are not affected by the fading or noise of the

ON THE CLASS OF ARRAY-BASED APM-LDPC CODES [PDF]
Journal of Algebraic Systems, 2021 We construct an explicit class of affine permutation matrix low-density parity-check (APM-LDPC) codes based on the array parity-check matrix by using two affine maps f (x) = x-1 and g(x) = 2x-1 on Z_m, where m is an odd prime number, with girth 6 and ...

Non-binary protograph low-density parity-check codes for space communications [PDF]
, 2012 Protograph-based non-binary low-density parity-check (LDPC) codes with ultra-sparse parity-check matrices are compared with binary LDPC and turbo codes (TCs) from space communication standards.
