Resumo: : Este trabalho aborda a aplicação da predição linear na análise de sinais discretos. Examinaremos a sua utilização no problema de estimação de freqüências de um sinal sujeito à ruído. O critério baseado nos mínimos-quadrados será utilizado para a obtenção do preditor ótimo nas formas forward, backward e forward-backward. A ferramenta de decomposição em valores singulares (DVS) será utilizada para a obtenção da solução de norma-mínima para esses preditores. Tal solução particular será detalhadamente estudada para investigar o comportamento dos zeros do polinômio associado ao filtro de erro de predição. A análise desenvolvida trouxe contribuições ao conhecimento dos métodos baseados na norma-mínima, as quais propiciaram a elaboração de uma proposta de um novo método para detecção de freqüências baseado no método FBLP Modificado. Os resultados de simulações obtidos para o método proposto mostram uma SNR de limiar inferior àquela obtida para o método FBLP Modificado. Os resultados também indicam que o novo método é capaz de estimar freqüências em SNR's inferiores àquelas obtidas mesmo para o método da Máxima Verossimilhança
Abstract: This work is concerned with the application of the linear prediction on the discrete signals analysis, aiming the frequency estimation at low signal to noise ratios. The linear prediction is optimized using least squares criterion and each of the following forms: forward, backward, forward-backward. For each one of this cases, a minimum norm solution is obtained through singular value decomposition and a polynomial is formed using the optimized coefficients. The study of the behavior of their zeroes led to new insight into the minimum norm based frequency detection methods, allowing the proposal of a new method, based on the Modified FBLP. The simulation results have shown that this new method is able to detect frequencies at lower signal to noise ratios, even when compared with the Maximum Likelihood method

Повний текст джерелаFast or real-time identification of the spatiotemporal activation of Motor Units (MUs), functional units of the neuromuscular system, is fundamental in applications as prosthetic control and rehabilitation guidance but often dictates expensive computational times. Therefore, the thesis work was devoted to providing an algorithm that enables the real-time identification of MU spatial and temporal activation strategies by applying inverse methods on HD-sEMG (high-density surface electromyogram) signals from a grid placed over the Biceps Brachii (BB). For this purpose, we propose an innovative approach, that involves the use of the classical minimum norm inverse method and a 3D fitting curve interpolation, namely CFB-MNE approach. This method, based on inverse identification (minimum norm estimation) coupled to simulated motor unit action potential (MUAP) dictionary from a recent model and tested on simulations, allowed the real time localization of simulated individual motor units. A robustness analysis (anatomical, physiological, and instrumental modifications) was then performed to verify the efficiency of the proposed algorithm. Finally, the proposed algorithm was tested on MUs with realistic recruitment patterns giving promising results in both spatial and temporal identification. To conclude, a door to future perspectives was opened, according to the obtained promising results, suggesting the use of machine learning and artificial intelligence (AI) to further boost the performance of the proposed algorithm

Повний текст джерелаMixed architectures containing programmable devices and reconfigurable ones can provide calculation performance necessary to meet constraints of real-time applications. But the implementation and optimization of these applications on this kind of architectures is a complex task that takes a lot of time. In this context, we propose a rapid prototyping tool for this type of architectures. This tool is based on our extension of the Adequacy Algorithm Architecture methodology (AAA). It allows to automatically perform optimized partitioning and scheduling of the application operations on the target architecture components and generation of correspondent codes. We used this tool for the implementation of the motion estimator of the H.264/AVC on an architecture composed of a Nios II processor and Altera Stratix III FPGA. So we were able to verify the correct running of our tool and validate our automatic generator of mixed code

Повний текст джерелаThe main objective of this thesis is the study of integration of several radio interfaces within the same radio architecture. The selected application is standard UMTS, where modes TDD and FDD are intended to be implemented on the same terminal with a low complexity thanks to the reconfigurability concept. First, we start to study the both UMTS access techniques in order to facilitate their common implementation on the same material support. This lead to establish a low complexity receiver composed by an adapted filters and an equalizer at symbol time. To improve the ability of theses Iwo treatments to fight against the interferences, a channel estimator was developed to provide a parametric model channel. An innovating reconfigurability concept is applied to obtain a reconfigurable hybrid receiver in spite of the difference between mode TDD and FDD. Finally, a decision entity improves the receiver flexibility by managing the resources of each treatment according to the state of the channel

Повний текст джерелаThe development of modal antennas which are radiation pattern reconfigurable active antennas, but not arrays, started in order to implement beam forming in cellphones. This solution is generally made with an antenna array, which is very difficult, even impossible, in a mobile phone. Beam forming could improve the link budget and increase the data rate. The first aim of this thesis is the development of modal antennas for LTE standard. Three modal antennas concepts were presented. The first one is a reconfigurable “folded loop” active antenna by permutation of feed and ground points. The second one is a solution to gather the main and the diversity antenna in the bottom part of the phone, and to support MIMO and carrier aggregation, which are two features of LTE. The last one optimizes the use of the second antenna in LTE MIMO systems in order to perform beam forming. These modal antennas will provide their real potential only by being used by a driving algorithm which will choose the best mode or configuration according to the situation. So, the second aim of this thesis is the development of smart modal antenna driving algorithms. The first algorithm, developed and patented by Ethertronics, has the specificity to predict, at each moment, which mode will be the best for the next moment, by using baseband data for LTE. The second algorithm is deterministic and can estimate and track the direction of arrival of the signal. Then, it selects the mode which has the best gain in this direction in order to improve the link budget
