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 ...

Abstract: Low-density parity-check (LDPC) codes deliver very good performance when decoded with the BP algorithm. Unfortunately, this algorithm has the disadvantage to be complex for implementation.

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 ...

Low-Density Parity-Check (LDPC) approaches Shannon-limit performance for binary field and long code lengths. However, performance of binary LDPC code is degraded when the code word length is small. An ...

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 ...

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 ...

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): ...
