Array Convolutional Low-Density Parity-Check Codes [PDF]
IEEE Communications Letters, 2013 This paper presents a design technique for obtaining regular time-invariant low-density parity-check convolutional (RTI-LDPCC) codes with low complexity and good performance. We start from previous approaches which unwrap a low-density parity-check (LDPC)

Low-Density Parity-Check Codes and Their Rateless Relatives [PDF]
IEEE Communications Surveys and Tutorials, 2011 This survey guides the reader through the extensive open literature that is covering the family of low-density parity-check LDPC codes and their rateless relatives. In doing so, we will identify the most important milestones that have occurred since their conception until the current era and elucidate the related design problems and their respective ...

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 ...

A New Method for Building Low-Density-Parity-Check Codes
International Journal of Technology, 2019 This paper proposes a new method for building low-density-parity-check codes, exempt of cycle of length 4, based on a circulant permutation matrix, which needs very little memory for storage it in the encoder and a dual diagonal structure is applied ...

Weight Distribution of Low-Density Parity-Check Codes
IEEE Transactions on Information Theory, 2006 We derive the average weight distribution function and its asymptotic growth rate for low-density parity-check (LDPC) code ensembles. We show that the growth rate of the minimum distance of LDPC codes depends only on the degree distribution pair. It turns out that capacity-achieving sequences of standard (unstructured) LDPC codes under iterative ...

Double-Layer Low-Density Parity-Check Codes over Multiple-Input Multiple-Output Channels [PDF]
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.

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.
