ROBUST CODES CREATION BASED ON BENT-FUNCTIONS AND WAVELET TRANSFORMATION [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2018
Subject of Research. This paper presents an application of wavelet transformation and bent-functions in the creation of non-linear robust codes. The usage of wavelet decompositions gives the possibility to create a large number of different designs of ...

A study of differences between bent functions constructed using Rothaus method and randomly generated bent functions

open access: yesJournal of Telecommunications and Information Technology, 2003
Bent functions, having the highest possible nonlinearity, are among the best candidates for construction of S-boxes. One problem with bent functions is the fact that they are hard to find among randomly generated set of Boolean functions already for 6 ...

Asymptotically Optimal Codebooks Derived From Generalised Bent Functions

open access: yesIEEE Access, 2020
Codebooks are required to have small inner-product correlation in many practical applications, such as direct spread code division multiple access communications, space-time codes and compressed sensing.

Decomposing bent functions [PDF]

open access: yesIEEE Transactions on Information Theory, 2003
In a recent paper , it was shown that the restrictions of bent functions to subspaces of codimension 1 and 2 are highly nonlinear. Here, we present an extensive study of the restrictions of bent functions to affine subspaces. We propose several methods which are mainly based on properties of the derivatives and of the dual of a given bent function.

MIMO CPW-Fed Bent Antenna Based USB Dongle for ECMA-368 WPANs

open access: yesAdvanced Electromagnetics, 2021
A multiple-input-multiple-output (MIMO) ultra-wideband (UWB ) printed bent antenna, suitable for MB-OFDM ECMA-368 system integration with the wireless universal serial-bus (WUSB) dongle is proposed.

Using Inclusion / Exclusion to find Bent and Balanced Monomial Rotation Symmetric Functions

open access: yesJournal of Mathematical Cryptology, 2021
There are many cryptographic applications of Boolean functions. Recently, research has been done on monomial rotation symmetric (MRS) functions which have useful cryptographic properties.

Construction of bent functions from near-bent functions

open access: yesJournal of Combinatorial Theory, Series A, 2009
A function \(f\) from an \(n\)-dimensional vector space \(V_n\) over \(\mathbb{F}_2\) into \(\mathbb{F}_2\) is called bent (near-bent) if its Walsh transform \(\hat{f}(u) = \sum_{x\in V_n}(-1)^{f(x)+\langle u,x\rangle}\) where \(\langle\;,\;\rangle\) denotes any inner product on \(V_n\) takes values in \(\{\pm 2^{n/2}\}\) (\(\{0,\pm 2^{(n+1)/2 ...
