Abstract: In this paper, we present a simplification of log-BP algorithm which is able to reduce iterative times of decoding algorithm and save the hardware resource of decoder for LDPC codes. This ...

Abstract: In this paper, we propose a scheduling method of the shuffled BP decoding algorithm for punctured LDPC codes. The number of iteration required to recover whole punctured variable nodes in ...

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 ...

In the evolving landscape of wireless communication, particularly in Beyond 5G (B5G) systems, channel coding must meet increasingly demanding requirements for reliability, adaptability, and low ...

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 ...

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 ...
