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 ...

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): ...
