The Analytical Description of Regular LDPC Codes Correcting Ability
The analytical description of regular LDPC (Low-Density Parity Check) codes correcting ability has been investigated. The statistical dependencies for the maximum number of corrected bits per the code word as a function of LDPC code word length and code ...

LDPC convolutional codes based on braided convolutional codes [PDF]
We introduce and analyze new constructions of LDPC convolutional codes and their tail-biting versions which are obtained from braided convolutional codes. The basic ideas behind the encoding and decoding architectures for these codes are presented. Additionally, asymptotic results concerning the iterative thresholds are shown for different ensembles ...

Spatially Coupled LDPC Codes Constructed from Protographs
In this paper, we construct protograph-based spatially coupled low-density parity-check (SC-LDPC) codes by coupling together a series of L disjoint, or uncoupled, LDPC code Tanner graphs into a single coupled chain.

Iterative decoding of SOVA and LDPC product code for bit-patterned media recoding
The demand for high-density storage systems has increased due to the exponential growth of data. Bit-patterned media recording (BPMR) is one of the promising technologies to achieve the density of 1Tbit/in2 and higher.

A construction of the high-rate regular quasi-cyclic LDPC codes
In this paper, a scheme to construct the high-rate regular quasi-cyclic low-density parity-check (QC-LDPC) codes is developed based on the finite geometry low-density parity-check (LDPC) codes.

Minimum Distance Distribution of Irregular Generalized LDPC Code Ensembles
In this paper, the minimum distance distribution of irregular generalized LDPC (GLDPC) code ensembles is investigated. Two classes of GLDPC code ensembles are analyzed; in one case, the Tanner graph is regular from the variable node perspective, and in ...

On the performance of 1-level LDPC lattices
The low-density parity-check (LDPC) lattices perform very well in high dimensions under generalized min-sum iterative decoding algorithm. In this work we focus on 1-level LDPC lattices.

Novel construction of QC-LDPC codes with modified 2-D GRS codes
The construction method for QC-LDPC (quasi-cyclic low density parity-check) code with modified two-dimensional generalized reed-solomon (2-D GRS) code is proposed using the generator polynomial of GRS code,so thus the constructed code can have better ...

Rateless Coded Multi-User Uplink Transmission With Distributed Fronthaul Compression in Cloud RAN
In this paper, we design the rateless coded uplink transmission in cloud radio access network (C-RAN) with two users, two remote radio heads (RRHs), and one baseband processing unit (BBU) pool under block fading channel.

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications
In this paper, we propose a low-density parity check (LDPC) code design scheme that improves the performance of the existing genetic algorithm-based LDPC scheme. In particular, we enhance the performance of the LDPC code by removing the girth-4 property
