Enumerators for Protograph-Based Ensembles of LDPC and Generalized LDPC Codes

IEEE Transactions on Information Theory, 2011
Protograph-based LDPC and generalized LDPC (G-LDPC) codes have the advantages of a simple design procedure and highly structured encoders and decoders. The design of such “protograph-based codes” relies on what is effectively a computer-based search. As such, following Gallager, it is prudent to restrict the search to a “good ensemble,” for example, an

Block-LDPC: a practical LDPC coding system design approach

IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2005
This paper presents a joint low-density parity-check (LDPC) code-encoder-decoder design approach, called Block-LDPC, for practical LDPC coding system implementations. The key idea is to construct LDPC codes subject to certain hardware-oriented constraints that ensure the effective encoder and decoder hardware implementations.

Comprehensive Study on CC-LDPC, BC-LDPC and Polar Code

2020 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2020
Channel coding scheme is very crucial for the next sixth generation (6G) mobile communication. In this paper, we investigate the encoding and decoding methods of the state-of-the-art channel codes, which include the convolutional code LDPC (CC-LDPC), block code LDPC (BC-LDPC) and polar code to access the benefits from CC-LDPC.

Irregular LDPC codes as concatenation of regular LDPC codes

IEEE Communications Letters, 2005
In this letter, the construction of irregular LDPC codes obtained by concatenating regular ones is considered. These codes are analyzed for the binary symmetric channel (BSC). It is shown via proper distribution evolution that such concatenated codes have in general a threshold value weaker (but not necessarily much different) than their unconstrained ...

Overview of LDPC Codes

7th IEEE International Conference on Computer and Information Technology (CIT 2007), 2007
In light of the history of LDPC codes and relevant research advances in recent years, this paper probes into the encoding and decoding techniques related to this capacity-approaching error-correction technology. Besides the general expression as an equation, LDPC codes can also be examined with a Tanner graph.

Iterative LDPC-LDPC product code for bit patterned media

2016 Asia-Pacific Magnetic Recording Conference Digest (APMRC), 2016
Bit patterned media aims at high density recording of more than 10 Tb per square inch, but a burst error mostly occurred by media defects, and data write failure can be a serious problem. However, if the burst errors are compensated by erasure decoding, the performance of low-density parity check (LDPC) code, which is a strong candidate for the error ...
