Chaotic block cryptosystem using high precision approaches to tent map
(Elsevier B.V., 2011)
Spectral properties of chaotic signals generated by the skew tent map
(ELSEVIER SCIENCE BV, 2010)
Chaotic signals have been considered potentially attractive in many signal processing applications ranging from wideband communication systems to cryptography and watermarking. Besides, some devices as nonlinear adaptive ...
A family of dissipative two-dimensional mappings: Chaotic, regular and steady state dynamics investigation
(Elsevier B.V., 2014-02-01)
Some dynamical properties for a family of two dimensional mappings controlled by three parameters are considered in this paper. For null dissipation and depending on the other control parameters, diffusion in phase space ...

On the dynamics of two-dimensional dissipative discontinuous maps
(2020-02-01)
Some dynamical properties for a dissipative two-dimensional discontinuous standard mapping are considered. The mapping, in action-angle variables, is parameterized by two control parameters; namely, k ≥ 0 controlling the ...
Spectral properties of chaotic signals with applications in communications
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This paper investigates the characteristics of the Power Spectral Density (PSD) of chaotic signals generated by skew tent maps. The influence of the Lyapunov exponent on the autocorrelation sequence and on the PSD is ...
Stochastic degradation of the fixed-point version of 2D-chaotic maps
(Elsevier, 2017-11)
This paper deals with a family of interesting 2D-quadratic maps proposed by Sprott, in his seminal paper [1], related to “chaotic art”. Our main interest about these maps is their great potential for using them in digital ...
On the localization of invariant Tori in a family of generalized standard mappings and its applications to scaling in a chaotic sea
(2018-01-01)
The localization of the last invariant spanning curve - also known as the last invariant tori - in a family of generalized standard mappings is discussed. The position of the curve dictates the size of the chaotic sea hence ...
