On the classification of perfect codes : side class structures

open access: yes, 2006
The side class structure of a perfect 1-error correcting binary code (hereafter referred to as a perfect code) C describes the linear relations between the coset representatives of the kernel of C.

The partial order of perfect codes associated to a perfect code

open access: yesAdvances in Mathematics of Communications, 2007
It is clarified whether or not ''full rank perfect 1-error correcting binary codes act like primes in the family of all perfect 1-error correcting binary codes''. Thereby the well known connection between perfect 1-error correcting binary codes and tilings will be discussed and used.

The (non-)existence of perfect codes in Lucas cubes

open access: yesپژوهش‌های ریاضی, 2022
A Fibonacci string of length $n$ is a binary string $b = b_1b_2ldots b_n$ in which for every $1 leq i < n$, $b_icdot b_{i+1} = 0$. In other words, a Fibonacci string is a binary string without 11 as a substring.

Concurrent Codes: A Holographic-Type Encoding Robust against Noise and Loss. [PDF]

open access: yesPLoS ONE, 2016
Concurrent coding is an encoding scheme with 'holographic' type properties that are shown here to be robust against a significant amount of noise and signal loss.

Embedding in q-ary 1-perfect codes and partitions [PDF]

open access: yesDiscrete Mathematics, 2014
It is proved that every 1-error-correcting code over a finite field can be embedded in a 1-perfect code of some larger length. Embedding in this context means that the original code is a subcode of the resulting 1-perfect code and can be obtained from it

Construction of Fractional Repetition Codes with Variable Parameters for Distributed Storage Systems

open access: yesEntropy, 2016
In this paper, we propose a new class of regular fractional repetition (FR) codes constructed from perfect difference families and quasi-perfect difference families to store big data in distributed storage systems.

Perfect 2-colorings of the cubic graphs of order less than or equal to 10

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Perfect coloring is a generalization of the notion of completely regular codes, given by Delsarte. A perfect -coloring of a graph with colors is a partition of the vertex set of into m parts , . . .
