Abstract: A new method is presented for low-complexity near-maximum-likelihood (ML) decoding of low-density parity-check (LDPC) codes over the additive white Gaussian noise channel. The proposed ...

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 ...

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

IEEE802.16e準拠のLDPC復号器の開発を行った。Bit-serial BP（Belief Propagation）アルゴリズムは、BPアルゴリズムの半分の繰り返し数で同等の特性が得られることより、このLDPC復号器にはBit-serial BPアルゴリズムを採用した。また、信頼度の低い対数尤度比の量子化 ...

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 ...

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 ...

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): ...
