Array Convolutional Low-Density Parity-Check Codes [PDF]
IEEE Communications Letters, 2014 This paper presents a design technique for obtaining regular time-invariant low-density parity-check convolutional (RTI-LDPCC) codes with low complexity and good performance. We start from previous approaches which unwrap a low-density parity-check (LDPC) block code into an RTI-LDPCC code, and we obtain a new method to design RTI-LDPCC codes with ...

British Educational Research Journal, EarlyView.Abstract The intersection of economic conditions and early years education has long been debated, particularly where financial constraints shape educational practice and professional realities. Türkiye, characterised by high inflation and structural vulnerabilities in purchasing power parity, provides a critical context for examining how economic ...

Design of low-density parity-check codes: An overview
, 2011 This article provides an overview of the conflicting design tradeoffs of low-density parity-check (LDPC) codes and thus advocates a more holistic approach to their design for wireless channels.

Planar Quantum Low-Density Parity-Check Codes with Open Boundaries
PRX QuantumAlthough high-threshold and low-overhead quantum low-density parity-check (qLDPC) codes, such as bivariate bicycle (BB) codes, can reduce the physical-qubit cost by an order of magnitude compared to the Kitaev toric code, their torus layout remains ...

Reordered static layered schedule for 5G low‐density parity‐check codes
Electronics LettersThe error performance of the 5G low‐density parity‐check codes is significantly impacted by the update order of layers. At present, the row degree (RD) and the number of punctured bits (PBs) are widely used to decide the update order of layers. Here, the

Entanglement-assisted Quasi-cyclic Quantum Low-density Parity-check Codes over Qubits [PDF]
QuantumWe construct several families of entanglement-assisted quasi-cyclic quantum LDPC (EA-QC-QLDPC) codes via structured tilings of permutation matrices. The entanglement-unassisted portion of the joint Tanner graph of the proposed EA-QC-QLDPC code derived ...

From Product Codes to Structured Generalized LDPC Codes [PDF]
, 2010 Product codes, due to their relatively large minimum distance, are often seen as a natural solution for applications requiring low error floors.

Biotechnology and Bioengineering, EarlyView.ABSTRACT A method to select Escherichia coli citrate synthase variants having reduced activity was developed based initially on the increased generation of acid, observed visually by prolonged color change in the pH indicator bromocresol purple. Five hundred fifty‐two potential variants were isolated and each were cultured on glucose as sole carbon ...

Construction of regular quasi-cyclic protograph LDPC codes based on Vandermonde matrices
, 2008 In this contribution, we investigate the attainable performance of quasi-cyclic (QC) protograph Low-Density Parity-Check (LDPC) codes for transmission over both Additive White Gaussian Noise (AWGN) and uncorrelated Rayleigh channels.
