Random linear codes in steganography [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2016
Syndrome coding using linear codes is a technique that allows improvement in the steganographic algorithms parameters. The use of random linear codes gives a great flexibility in choosing the parameters of the linear code.

On the List-Decodability of Random Linear Codes [PDF]

open access: yesProceedings of the forty-second ACM symposium on Theory of computing, 2010
For every fixed finite field $\F_q$, $p \in (0,1-1/q)$ and $\epsilon > 0$, we prove that with high probability a random subspace $C$ of $\F_q^n$ of dimension $(1-H_q(p)-\epsilon)n$ has the property that every Hamming ball of radius $pn$ has at most $O(1/\

Improved List-Decodability of Random Linear Binary Codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2021
There has been a great deal of work establishing that random linear codes are as list-decodable as uniformly random codes, in the sense that a random linear binary code of rate $1 - H(p) - ε$ is $(p,O(1/ε))$-list-decodable with high probability. In this work, we show that such codes are $(p, H(p)/ε+ 2)$-list-decodable with high probability, for any $p \

Squares of Random Linear Codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2015
Given a linear code $C$, one can define the $d$-th power of $C$ as the span of all componentwise products of $d$ elements of $C$. A power of $C$ may quickly fill the whole space. Our purpose is to answer the following question: does the square of a code "typically" fill the whole space?

Punctured Low-Bias Codes Behave Like Random Linear Codes

open access: yes2022 IEEE 63rd Annual Symposium on Foundations of Computer Science (FOCS), 2022
Random linear codes are a workhorse in coding theory, and are used to show the existence of codes with the best known or even near-optimal trade-offs in many noise models. However, they have little structure besides linearity, and are not amenable to tractable error-correction algorithms.

Quantum Error Correction Via Noise Guessing Decoding

open access: yesIEEE Access, 2023
Quantum error correction codes (QECCs) play a central role in both quantum communications and quantum computation. Practical quantum error correction codes, such as stabilizer codes, are generally structured to suit a specific use, and present rigid code

A Shannon-Theoretic Approach to the Storage–Retrieval Trade-Off in PIR Systems

open access: yesInformation, 2023
We consider the storage–retrieval rate trade-off in private information retrieval (PIR) systems using a Shannon-theoretic approach. Our focus is mostly on the canonical two-message two-database case, for which a coding scheme based on random codebook ...

On linear index coding for random graphs [PDF]

open access: yes2012 IEEE International Symposium on Information Theory Proceedings, 2012
A sender wishes to broadcast an n character word x in F^n (for a field F) to n receivers R_1,...,R_n. Every receiver has some side information on x consisting of a subset of the characters of x. The side information of the receivers is represented by a graph G on n vertices in which {i,j} is an edge if R_i knows x_j.

Soft Interference Cancellation for Random Coding in Massive Gaussian Multiple-Access

open access: yesEntropy, 2021
In 2017, Polyanskiy showed that the trade-off between power and bandwidth efficiency for massive Gaussian random access is governed by two fundamentally different regimes: low power and high power. For both regimes, tight performance bounds were found by

Blind Interleaver Parameters Estimation Using Kolmogorov–Smirnov Test

open access: yesSensors, 2021
The use of error-correcting codes (ECCs) is essential for designing reliable digital communication systems. Usually, most systems correct errors under cooperative environments.
