Decoding of Repeated-Root Cyclic Codes up to New Bounds on Their Minimum Distance

open access: yesProblems of Information Transmission, 2015
The well-known approach of Bose, Ray-Chaudhuri and Hocquenghem and its generalization by Hartmann and Tzeng are lower bounds on the minimum distance of simple-root cyclic codes. We generalize these two bounds to the case of repeated-root cyclic codes and

Some Constacyclic Codes over Finite Chain Rings [PDF]

open access: yes, 2012
For $\lambda$ an $n$-th power of a unit in a finite chain ring we prove that $\lambda$-constacyclic repeated-root codes over some finite chain rings are equivalent to cyclic codes. This allows us to simplify the structure of some constacylic codes.

Commuting-projector Hamiltonians for chiral topological phases built from parafermions [PDF]

open access: yes, 2018
We introduce a family of commuting-projector Hamiltonians whose degrees of freedom involve $\mathbb{Z}_{3}$ parafermion zero modes residing in a parent fractional-quantum-Hall fluid.

Quantum Codes Constructed From Repeated-Root Cyclic Codes

open access: yesJournal of Physics: Conference Series, 2018
In this paper, we use q-cyclotomic cosets modulo n = q − 1 and generator polynomial to describe repeated-root cyclic codes of length N = pαn. We determine the condition under which a repeated-root cyclic code contains its dual code. Then, for q = 2a, we give a class of dual-containing repeated-root cyclic codes.

Repeated-root Constacyclic Codes with Optimal Locality

open access: yes, 2021
A code is called a locally repairable code (LRC) if any code symbol is a function of a small fraction of other code symbols. When a locally repairable code is employed in a distributed storage systems, an erased symbol can be recovered by accessing only a small number of other symbols, and hence alleviating the network resources required during the ...

Repeated-root cyclic codes [PDF]

open access: yesIEEE Transactions on Information Theory, 1991
In the theory of cyclic codes, it is common practice to require that (n,q)=1, where n is the word length and F/sub q/ is the alphabet. It is shown that the even weight subcodes of the shortened binary Hamming codes form a sequence of repeated-root cyclic codes that are optimal.

Fittino, a program for determining MSSM parameters from collider observables using an iterative method [PDF]

open access: yes, 2005
Provided that Supersymmetry (SUSY) is realized, the Large Hadron Collider (LHC) and the future International Linear Collider (ILC) may provide a wealth of precise data from SUSY processes.

Uncertainty analysis in the simulation of effective seepage flow through earth dams with the Monte Carlo algorithm and machine learning [PDF]

open access: yesمدل‌سازی و مدیریت آب و خاک
IntroductionThe cost of building dams is very high and their failure can be hazardous. On the other hand, they are vital for every country as freshwater storage.

List decoding of repeated codes [PDF]

open access: yes, 2013
Assuming that we have a soft-decision list decoding algorithm of a linear code, a new hard-decision list decoding algorithm of its repeated code is proposed in this article. Although repeated codes are not used for encoding data, due to their parameters,

Algorithms For Extracting Timeliness Graphs [PDF]

open access: yes, 2010
We consider asynchronous message-passing systems in which some links are timely and processes may crash. Each run defines a timeliness graph among correct processes: (p; q) is an edge of the timeliness graph if the link from p to q is timely (that is ...
