Low-Density Parity-Check Codes

2013
Low-density parity-check (LDPC) codes were introduced in 1960 by R. Gallager [1] in his Phd thesis. He already introduced the iterative method for decoding LDPC codes. However, also due to their computational and implementation complexity the iterative decoding was largely ignored.

Low Density Parity Check Codes

2015
Low density parity check (LDPC) codes are forward error-correction codes, invented by Robert Gallager in his MIT Ph.D. dissertation, 1960. The LDPC codes are ignored for long time due to their high computational complexity and domination of highly structured algebraic block and convolutional codes for forward error correction.

Low-Density Parity-Check Code Constructions

2014
Low-density parity-check (LDPC) codes are a class of linear block code capable of performing extremely close to the capacity of a channel as defined by Shannon. The purpose of this chapter is to provide an overview of the basic ideas, as well as the main results, in the field of LDPC code construction. No attempt could possibly be made to include every

Low-density parity check codes over GF(q)

IEEE Communications Letters, 1998
Gallager's (1962) low-density binary parity check codes have been shown to have near-Shannon limit performance when decoded using a probabilistic decoding algorithm. We report the empirical results of error-correction using the analogous codes over GF(q) for q>2, with binary symmetric channels and binary Gaussian channels.

Low-Density Parity-Check (LDPC) Codes

2012
In this chapter, low-density parity-check (LDPC) codes, a class of powerful iteratively decodable error correcting codes, are introduced. The chapter first reviews some basic concepts and results in information theory such as Shannon’s channel capacity and channel coding theorem. It then overviews the Flash memory channel model.
