On the performance of 1-level LDPC lattices

open access: yes, 2013
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.

Generic 5G NR LDPC Encoder Architecture Optimized for Area and Throughput

open access: yesJournal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
Physical Downlink Shared Channel (PDSCH) in 5G New Radio (NR) uses LDPC codes as the channel coding solution for their efficient error‐correcting performance and suitability for high‐speed communications. To meet the high‐throughput requirements of the 5G NR technology, this paper discusses different 5G NR LDPC encoder architectures that enable ...

A High Throughput Implementation of QC-LDPC Codes for 5G NR

open access: yesIEEE Access, 2019
Quasi-cyclic low-density parity-check (QC-LDPC) codes are the choice for data channels in the fifth generation (5G) new radio (NR). At the transmitter side, code bits from the QC-LDPC encoder are delivered to the rate matcher.

Parity-Check Network Coding for Multiple Access Relay Channel in Wireless Sensor Cooperative Communications

open access: yesEURASIP Journal on Wireless Communications and Networking, 2010
A recently developed theory suggests that network coding is a generalization of source coding and channel coding and thus yields a significant performance improvement in terms of throughput and spatial diversity.

New Technique for Improving Performance of LDPC Codes in the Presence of Trapping Sets

open access: yesEURASIP Journal on Wireless Communications and Networking, 2008
Trapping sets are considered the primary factor for degrading the performance of low-density parity-check (LDPC) codes in the error-floor region. The effect of trapping sets on the performance of an LDPC code becomes worse as the code size decreases. One
