Reduced-complexity decoding implementation of QC-LDPC codes with modified shuffling

EURASIP Journal on Wireless Communications and Networking, 2021
Layered decoding (LD) facilitates a partially parallel architecture for performing belief propagation (BP) algorithm for decoding low-density parity-check (LDPC) codes.

Stopping Set Distributions of Some Linear Codes [PDF]

, 2010
Stopping sets and stopping set distribution of an low-density parity-check code are used to determine the performance of this code under iterative decoding over a binary erasure channel (BEC).

Untainted Puncturing for Irregular Low-Density Parity-Check Codes [PDF]

IEEE Wireless Communications Letters, 2012
Puncturing is a well-known coding technique widely used for constructing rate-compatible codes. In this paper, we consider the problem of puncturing low-density parity-check codes and propose a new algorithm for intentional puncturing. The algorithm is based on the puncturing of untainted symbols, i.e.

Population pharmacokinetics and dosing of dispersible moxifloxacin formulation in children with rifampicin‐resistant tuberculosis

British Journal of Clinical Pharmacology, EarlyView.
Aims Moxifloxacin is a priority drug for treating rifampicin‐resistant tuberculosis (RR‐TB). We assessed the pharmacokinetics of a child‐friendly, dispersible 100 mg tablet moxifloxacin formulation (dispersed in water) compared to the standard 400 mg non‐dispersible formulation (crushed and suspended in water) in children and evaluated current dosing ...

Bilayer Low-Density Parity-Check Codes for Decode-and-Forward in Relay Channels [PDF]

IEEE Transactions on Information Theory, 2006
This paper describes an efficient implementation of binning for decode-and-forward (DF) in relay channels using low-density parity-check (LDPC) codes. Bilayer LDPC codes are devised to approach the theoretically promised rate of the DF relaying strategy ...

Cryptanalysis of Two McEliece Cryptosystems Based on Quasi-Cyclic Codes

, 2010
We cryptanalyse here two variants of the McEliece cryptosystem based on quasi-cyclic codes. Both aim at reducing the key size by restricting the public and secret generator matrices to be in quasi-cyclic form.

Message passing algorithms for non-linear nodes and data compression [PDF]

, 2005
The use of parity-check gates in information theory has proved to be very efficient. In particular, error correcting codes based on parity checks over low-density graphs show excellent performances.

Utilising Artificial Intelligence to Enhance Firm Circular Economy Maturity: A Thematic Review via Machine Learning

Business Strategy and the Environment, EarlyView.
ABSTRACT Despite the environmental imperative of a transition to a circular economy (CE), the current literature finds that globally firms are being slow to engage with such a transition. In this context, our thematic review explores how artificial intelligence (AI) might accelerate firm CE transition.
