On the design of low-density parity-check codes within 0.0045 dB of the Shannon limit
IEEE Communications Letters, 2001We develop improved algorithms to construct good low-density parity-check codes that approach the Shannon limit very closely. For rate 1/2, the best code found has a threshold within 0.0045 dB of the Shannon limit of the binary-input additive white ...

VLSI Design for Low-Density Parity-Check Code Decoding
IEEE Circuits and Systems Magazine, 2011Low-Density Parity-check (LDPC) code, being one of the most promising near-Shannon limit error correction codes (ECCs) in practice, has attracted tremendous attention in both academia and industry since its rediscovery in middle 1990's.

Design of Low-Density Parity Check Codes for 5G New Radio
IEEE Communications Magazine, 2018Turbo codes, prevalent in most modern cellular devices, are set to be replaced by LDPC codes as the code for forward error correction. This transition was ushered in mainly because of the high throughput demands for 5G New Radio (NR).

A novel parity-check matrix design for low-density parity-check (LDPC) codes is described. By eliminating the routing problem associated with LDPC codes, the design results in a small implementation area, and the codes have outstanding error-rate ...

Analysis of scaling soft information on low density parity check code
, 2003Density evolution is used to analyse the scaling of soft information in the iterative decoding of low density parity check codes. Based on the min-sum algorithm and Gaussian approximation, the thresholds are evaluated with various scaling factors.

Structured low-density parity-check codes
IEEE Signal Processing Magazine, 2004This article describes the different methods to design regular low density parity-check (LDPC) codes with large girth. In graph terms, this corresponds to designing bipartite undirected regular graphs with large girth. Large girth speeds the convergence of iterative decoding and improves the performance at least in the high SNR range, by slowing down ...
