In the past twenty years, chaos-based communication systems have been studied, considering the possibility of generating wideband signals by simple electronic circuits, hence low complexity in transceiver. The aim of this thesis is to study the chaos-based wideband transmission systems relying on the properties of chaotic attractors. Firstly, a dynamical system is selected and studied, allowing to generate the chaotic signals with a periodic component. The analysis of such chaotic cyclic attractors (CCA) shows the specific properties. Then, two CCA-based modulation schemes are proposed, with the simple noncoherent detections realized by observing the specific properties of the received signals. The performance evaluation of CCA-based systems in the additive white Gaussian noise (AWGN) channel shows a better noise performance with long symbol duration, compared to the one of differentially chaos shift keying (DCSK). In addition, they have a comparable multipath performance in the 2. 4 GHz ISM environment

The amount of data used in information technology is increasing dramatically. This comes with the proliferation of highly advanced electronic technologies. The thermal issues, rising as an effect of such large data processes, impose the usage of novel technologies and paradigms in place of CMOS circuits. Spintronic devices are one of many alternatives proposed so far in the literature. In this work, we consider a spintronic device called nano-contact vortex oscillator (NCVO), which has recently begun to gain attention due to its rich and variable dynamics. This oscillators is operated by an bias DC current and subjected in a magnetic field, that determines it output dynamics. The practical use of the NCVO requires the existence of an accurate model that imitates its output magnetization and the vortex's trajectory rotating around the center in the upper layer of the device. These two variables are needed for the calculation of the equivalent resistance of the NCVO. For that, we build in this PhD work a model for the NCVO producing these two variables using a reservoir computing approach called conceptor-driven network. The network is trained on NCVO data gained by micromagnetic simulation. The built model successfully captures the NCVO dynamics in its different regimes (chaotic, periodic, and quasi- periodic) with an easy shift between regimes. The same network is used then for the detection of chaos in the input-times series. The proposed chaos-detection method has shown to be efficient and more robust compared to existing methods. Finally, the NCVO model is exploited for truly random number generation (TRNG) where a hardware design, fed by a chaotic signal generated by the model, is proposed. This design has shown the ability to compete existing RNG techniques in terms of speed, cost, and quality
Bzikha, Ihssane. "Comparison and development of advanced wiring fault detection methods on coaxial cables". Thesis, Limoges, 2019. http://www.theses.fr/2019LIMO0119.
In this thesis, we present new approaches of soft fault detection and location in simple andcomplex wire networks. The idea is to find a new approach to overcome the difficulties withstandard reflectometry techniques. We prove that before applying post-treatment methods,denoising techniques should be applied, such as empirical mode decomposition (EMD), localmean decomposition (LMD), or the discrete wavelet transform (DWT). These three methodsdecompose a signal into multiple levels to threshold them before signal reconstruction.Testing several applications shows that EMD is the most efficient method, although it hassome limitations as side effects. After the denoising step, the wiring faults can be detected.Time–frequency analysis is employed at this step. This approach, based on the FourierTransform, is able to detect wiring faults only if the noise level is low. To overcome thisdifficulty, the Bayesian approach is beneficial when system complexity increases. Its responseis based on estimation of prior parameters and prior distributions. In this work, the Bayesianapproach is applied via a formal mathematical study followed by simulation results validatingthe proposed approach, with analysis of the parameters that affect the method’s performance.In the domain of soft fault location, we derive a chaos time domain reflectometry approachbased on chaotic signal properties. Our simulation and experimental results prove that thismethod can synthesize signals and localize the soft fault position without the need forsupplemental methods

The work developed in this manuscript addresses the synchronization of chaotic systems. It is organized around two main axes: the observer synthesis and the mode detection. In a first step, we recall the main architectures of chaotic encryption systems and show how chaotic systems with polynomial nonlinearities or switched affine dynamics can be rewritten in a polytopic LPV form. A review of the main LMI based results for polytopic LPV observers synthesis is made. An extension to polytopic unknown input observers, both in the deterministic case and noisy or uncertain case, is proposed. These observers ensure chaos synchronization and information recovering in the framework of the following encryption systems: "parametric modulation", "chaotic switching", "two channels transmission" and "inclusion encryption". For affine switched systems used as a generator of chaos, the case where the discrete state is not available is considered. A unified presentation of mode detection methods based on parity spaces proposed in the literature for linear and affine switched discrete time systems is proposed. The problem of discernibility is the subject of a complete study. An approach to estimate time varying delays for affine switched discrete time systems, formulated in terms of mode detection, is proposed as a solution for delay injection encryption
