Low-Density Parity-Check (LDPC) Codes: A class of error-correcting codes characterised by sparse parity-check matrices that enable near-capacity performance in digital communications.

Technical Terms LDPC code: An error-correcting code with a sparse parity-check matrix that approaches Shannon’s capacity limit with efficient iterative decoding algorithms.

France launches criminal investigation into Musk’s X over algorithm manipulation The probe is based on complaints from a lawmaker and an unnamed senior civil servant.

In this letter, we investigate an efficient ADMM-based iterative decoder for binary LDPC codes. First, we build an mathematical programming equivalence of the maximum likelihood (ML) decoding problem ...

Abstract: In this paper a programmable and area-efficient decoder architecture supporting two main stream decoding algorithms for any Block-LDPC codes is presented. The novel decoder can be configured ...
