New quasi-cyclic codes over 5

Applied Mathematics Letters, 2002
AbstractOne of the most important problems of coding theory is to construct codes with best possible minimum distances. In this paper, we use the algebraic structure of quasi-cyclic codes and the BCH type bound on the minimum distance to search for quasicyclic codes over F5, the finite field with five elements, which improve the minimum distances of ...

Algebraic Quasi Cyclic Codes [PDF]

, 2017
في هذا الفصل، تتم مناقشة الرموز المزدوجة والثنائية ثنائية الدوران بناءً على الأعداد الأولية. العديد من الرموز المزدوجة الدوران مزدوجة ذاتيًا. تشكل الرموز الثنائية المزدوجة فئة مهمة من الرموز بسبب قدراتها القوية على تصحيح الأخطاء وبنيتها الرياضية الغنية. تمكن هذه البنية من تحديد توزيع الوزن الكامل للرمز.

Meniscus Pixel Printing for Contact‐Lens Vision Sensing and Robotic Control

Advanced Functional Materials, EarlyView.
A visual‐sensing contact lens is enabled by meniscus pixel printing (MPP), which rapidly patterns a 200 µm perovskite photodetector pixel in 1 s without masks, vacuum processing, or bulky equipment. A deep‐learning‐based super‐resolution reconstructs sparse on‐lens signals into 80 × 80 high‐resolution visual information, while AI‐driven eye‐tracking ...

Enhanced Li‐Ion Battery Performance with Hybrid MXene/GnR Electrodes: Heterojunctions and Engineered Architectures Supported by DFT Mechanistic Studies for Improved Rate Performance, Stability & Capacity

Advanced Functional Materials, EarlyView.
Lithium‐ion batteries (LIBs) remain central to energy storage but suffer from slow ion transport and degradation. Here, we present a binder‐free Ti3C2Tx MXene/GnR hybrid electrode with a porous 3D architecture formed via freeze casting. The structure enhances conductivity, ion transport, and stability, delivering 401 mAh/g, ∼97% efficiency, and 92 ...

Combinatorial design-based quasi-cyclic LDPC codes with girth eight

Digital Communications and Networks, 2018
This paper presents a novel regular Quasi-Cyclic (QC) Low Density Parity Check (LDPC) codes with column-weight three and girth at least eight. These are designed on the basis of combinatorial design in which subsets applied for the construction of ...

On quasi-cyclic codes as a generalization of cyclic codes

Finite Fields and Their Applications, 2012
In this article we see quasi-cyclic codes as block cyclic codes. We generalize some properties of cyclic codes to quasi-cyclic ones such as generator polynomials and ideals. Indeed we show a one-to-one correspondence between l-quasi-cyclic codes of length m and ideals of M_l(Fq)[X]/(X^m-1).
