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: A uniformly most powerful (UMP) belief propagation (BP) based algorithm is referred to as a simplified version of a BP algorithm with reduced complexity but performance loss for low density ...

Dynamic scheduling and decoding algorithms have become pivotal in advancing the performance of error-correcting codes. Recent innovations have focused on refining Low-Density Parity-Check (LDPC) codes ...

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 ...

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 ...

われわれは、FPGAを用いたIEEE802.16e準拠のLDPC復号器の開発を行ってきている。今回新たに開発した復号器では、BS-BPアルゴリズムの近似アルゴリズムであるBit-serial Normalized UMP BP（BS-NMBP）アルゴリズムを適用することにより、メモリ量の大幅な削減を達成した。

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 ...
