Abstract: Recently, both polar codes and low-density parity-check (LDPC) codes have been adopted by 3GPP eMBB scenario. Since both codes exist in one system, it is natural to consider the ...

Abstract: In this paper, we propose a new decoding algorithm that guarantees superior decoding performances for low-density parity-check (LDPC) codes without knowledge of channel parameters. Although ...

Nonbinary low-density parity-check (NB-LDPC) codes have emerged as a powerful tool in error correction, offering significant performance improvements over traditional ...

Low-Density Parity-Check (LDPC) codes represent a class of error-correcting codes that have fundamentally reshaped the field of digital communications. With their inherently sparse parity-check ...

This repository contains the implementation and examples for the BP-SF decoder used in: Fully Parallelized BP Decoding for Quantum LDPC Codes Can Outperform BP-OSD (HPCA 2026). The codebase provides a ...

LDPC Version 2: A C++ rewrite of the LDPCv1 package for decoding low density parity check checks. Warning, whilst efforts have been made to provide backwards ...

A new technique for efficient encoding of LDPC codes based on the known concept of Approximate Lower Triangulation (ALT) is introduced. The greedy permutation algorithm is presented to transform ...

HLS methodology allows the hardware design to be completed at a higher level of abstraction such as C/C++ algorithmic description. This provides significant time and cost savings, and paves the way ...

This paper describes an ASIP decoder template suitable for multi-standard Viterbi, Turbo and LDPC decoding. We show architecture fitness for WLAN, WiMAX and 3GPPLTE standards, although various other ...

January 6, 2025 - Global IP Core Sales - In the Sum Product Algorithm (SPA) for LDPC decoding the messages are sent from the check nodes to bit nodes after the SPA steps which are (for one iteration): ...
