Texto completo da fonteThis thesis studies two aspects of a vehicle access control system which relies on the estimation of a key's location to grant access.Firstly, within the context of a triangulation-based system, we study the optimisation of the switching sequence for switched antenna-arrays.A model is given to study the estimation of the parameters of sines received by a switched array, where sensors are not necessarily sampled synchronously.This model is relevant, but not exclusive, to industrial approaches to direction of arrival estimation, such as the one proposed by Bluetooth 5.1, which serves as our reference application.From the model, Cramér-Rao lower bounds are computed, and are used to define design criteria for switching sequences that do not rely on the array's geometry.These criteria's analytical forms allow us to highlight desirable properties in switching sequences, especially in the case where the signal's frequency is unknown.Strategies to build switching sequences are proposed, and numerically evaluated using the provided criteria. Comparison of the criteria with numerical bounds on direction of arrival for common array geometries shows that they are qualitatively linked.Secondly, within the context of a time of flight based system, we propose a system for passenger detection that relies solely on the localization system's original hardware.To achieve this, we propose to use support vector machines (SVM) to classify the channel impulse responses measured between the system's transmitters.A proof of concept is designed to demonstrate feasability, and data is collected on a prototype for further evaluation.By studying the available data, invariants are identified, and processing functions are proposed to translate these invariants to the SVM in order to improve performance.One of the proposed processing is shown to give performance gains for our application through experiments

Texto completo da fonteThe aim of this thesis is to characterize the theoretical capacity of the HF ionospheric channels and to improve the estimate in a receiver based on turbo-equalization. The capacity was treated by Lee and Ozarow for TDMA radio-communications using the hypothesis that each path attenuation is a Rayleigh random variable. This hypothesis is used without specifying any parameter. In a first part, this thesis presents an extension of Lee and Ozarow results for the non-stationary environments such as the ionospheric channel. A general theoretical capacity formula versus the Doppler spread is developed and it is an interesting contribution for the non-stationary channels. This one makes it possible to give a clear idea on the theoretical achievable bit rate of an ionospheric link affected by Doppler spread and inter symbol Interferences (ISI). The theoretical approach was finalized by an application to a real ionospheric communications link realized during the eclipse day (August 11, 1999). In a second part of this thesis, we studied and characterize the estimators likely to be used in the ionospheric turbo-equalizer based on linear filtering. Indeed, the estimators, such as Least Mean Squared (LMS), Recursive Least Squared (RLS) and Kalman filters (KF), were the subject of optimizations and comparisons in a real and simulated ionospheric environments. The optimization and comparisons, enabled us to choose the RLS and the Kalman estimators as being most performant (powerful) in the non stationary ionospheric channel. In a second part of this thesis, we studied and characterize the estimators likely to be used in the ionospheric turbo-equalizer based on linear filtering. Indeed, the estimators, such as Least Mean Squared (LMS), Recursive Least Squared (RLS) and Kalman filters (KF), were the subject of optimizations and comparisons in a real and simulated ionospheric environments. The optimization and comparisons, enabled us to choose the RLS and the Kalman estimators as being most performant (powerful) in the non stationary ionospheric channel. The last part of this thesis relates to the implementation of MMSE turbo-equalizer based on Soft Input Soft Output SISO principal and on RLS and Kalman estimators in the real and simulated ionospheric channel. The transmission is continie in time and the frame pattern is based on the STANAG 4285 HF modem specifications. The performances in bit error rate and the Mean Squared Error (MSE) were evaluated versus signal to noise ratio and Doppler spread. With respect to bit error rate and mean squared error, the estimations based on Kalman filter was more powerful than that using RLS algorithm

Texto completo da fonteSince the advent of the first French digital television broadcasts in 2005, the question of mobility reception has been often asked. Beyond the normative choices that tend to prefer the DVB-H standard to current DVB-T standards, the question of the uses and video quality remains a key issue. All the work already undertaken to make digital television mobile does not currently provide sufficient comfort for embedded upscale applications such as those desired in car, train, etc. . . To improve the Quality Of Service (QoS), a technique used is the diversity reception. In DVB-T, as applications and current studies do not provide information on propagation phenomena the choices of diversity algorithms, which are made in this context, are arbitrary. The CAVITY project proposes, with an analysis of the propagation channel, to develop and test different algorithms. This thesis is declines in three parts: The first part is to achieve a multi-antenna system able to achieve a temporal and spatial channel sounding in mobility conditions, through the reception of DVB-T broadcast signals. The second part is to achieve measurements to characterize the propagation channel phenomena in order to find a data diversity processing strategy. Finally, the third part is to propose new algorithms and parameters to improve reception mobility of DVB-T signal. The aim of this thesis is to improve visibility of propagation phenomena in DVB-T channel and regarding this knowledge to propose an adapted strategy for the reception of digital television in mobile conditions. By extension, this thesis may also enable to the television actors such as the DAB, T-DMB, ATSC to make the same choices to improve mobility reception of such digital systems that use the same basic modulation principle
Lepoitevin, Mathilde P. "Conception d'un nanopore unique pour mimer un canal biologique et pour la détection de bio-macromolécules". Thesis, Montpellier, 2016. http://www.theses.fr/2016MONTT226/document.
Texto completo da fonteArtificial nanopores are nanometer sized aperture made in synthetic thin films (polymer or inorganic). A single nanopore can be considered as a constitutive element from membranes. Recent advances in this field are bringing new tools for real time detection of target molecules at low concentration (fmol L-1). Biological channels inside the cell membrane are used as models to design solid-state nanopores. They allow ions or molecules transport through intra- and extra-cellular side, thanks to their high selectivity and their gating properties. Compared to their biological counterparts, limitations of the synthetic nanopores are their lack of selectivity and unresponsiveness towards external stimuli. However, the solid state presents several advantages compared to the biological ones, such as nanopores robustness, the control of the number of pores and a long lifetime (several days or weeks). Thus their surface functionalization would increase their selective transport properties, their abilities to detect biomolecules or to study more in details their fundamental mechanisms.In this thesis, we design first bi-functional nanopores, pH- and ligand-gated. To do it, we used biotin-avidin system grafted inside a polymeric nanopore. We demonstrated that it is possible to reversibly gate the nanopore with pH modulation. Moreover, we are able to detect protein labeled with biotin and antibodies by analyzing the current rectification. The major drawback comes from the irreversibility of its covalent bonds. By using a similar concept combined with polyelectrolytes, we obtain a reversible functionalization. Depending on the ligand, the ionic selectivity and the conduction properties can be modulated. Next, we focused on fundamental questions regarding polynucleotides translocation, and more precisely on the influence of the surface state of the nanopore (hydrophobicity, charge) when the Debye distance is similar to the pore diameter. We show that if the nanopore has the same charge as the polyAdenosine or polyCytosine, the translocation time decreases, and the energy barrier of entrance decreases compared to an uncharged hydrophobic nanopore. Then, by modifying the surface of the nanopore made in PET film, we are able to detect short single and double strand of DNA (10 to 40 bases). Finally, we tried to functionalize PET nanopores to avoid unspecific adsorption of proteins and to study the translocation of long fibrils of amyloids from lysozyme. This goal has not been entirely reach since we cannot claim that the fibrils translocate through the pore.In this thesis we show the interest and the need to functionalize the nanopores, to obtain biomimetic stimuli-responsive (pH and ligand), to avoid unspecific adsorption or to study transport properties with the nanopore. It is easy to upscale those techniques to multipores membranes. Thus it is possible to design membranes to enhance their ionic separation, target molecule detection or more generally filtration applications

Texto completo da fonteGrâce à une analogie avec les modulations codées, nous expliquons l'influence du schéma d'entrelacement, qui peut être réalisé au niveau des bits ou des symboles de modulation, sur les performances de la turbo-égalisation selon les caractéristiques temporelles des canaux de propagation. D'autre part, afin d'obtenir des performances satisfaisantes sur un modèle de canal ionosphérique, dont les caractéristiques de propagation sont réputées difficiles, nous étudions les différentes structures et algorithmes d'adaptation possibles pour les égaliseurs présents dans la turbo-égalisation. Puis nous présentons des améliorations de la conversion Maire-binaire sans information a priori. Une optimisation du mapping pour la conversion Maire-binaire avec information a priori de la turbo-égalisation est proposée et conduit à un gain de performances en terme de Taux d'Erreurs Binaires. Enfin nous comparons la turbo-égalisation à trois techniques alternatives : un système avec turbo-décodage, la technique multiporteuse COFDM, et un turbo-détecteur à treillis réduit.
