Wireless sensors embedded in high permittivity lossy media
The design of wireless sensors for operation embedded in a medium with high losses creates a series of additional constraints that should be taken into consideration at design stage to enhance sensor performance. In such ...
Sports broadcasting and multiple object tracking with deep learning methods
Since less than a decade ago, deep learning techniques started to dominate many different fields, revolutionizing the possibilities of artificial intelligence. Seeing their potential, industrial sectors started to invest ...
Nonlinear analysis of electro-acoustic frequency-selective devices for communications
Nowadays, mobile devices have become a key technology in our lives, making us become part of a connected world, in which millions of mobile handsets are sold every year. In order to satisfy the user demands, many mobile ...
Synthesis of acoustic wave filters : ladder and transversal topologies : towards a practical implementation
The meteoric growth of the mobile communication market for the last three decades has been strongly related with the evolution of the electroacoustic (EA) filter technology. With way over 5 billion cell phone users worldwide ...
Matrix completion with prior information in reproducing kernel Hilbert spaces
In matrix completion, the objective is to recover an unknown matrix from a small subset of observed entries. Most successful methods for recovering the unknown entries are based on the assumption that the unknown full ...
Self-supervised deep learning approaches to speaker recognition
In speaker recognition, i-vectors have been the state-of-the-art unsupervised technique over the last few years, whereas x-vectors is becoming the state-of-the-art supervised technique, these days. Recent advances in Deep ...
Injection of linguistic knowledge into neural text generation models
Language is an organic construct. It emanates from the need for communication and changes through time, influenced by multiple factors. The resulting language structures are a mix of regular syntactic and morphological ...
From hypothesis testing of quantum channels to secret sharing
The present thesis has three major thrusts: the first thrust presents a broad investigation of asymptotic binary hypothesis testing, when each hypothesis represents asymptotically many independent instances of a quantum ...
Design and performance analysis of advanced GNSS-R instruments back-end
GNSS reflectometry (GNSS-R) is a set of techniques that uses the reflected GNSS signals over the Earth’s surface as opportunity signals for remote sensing applications. In 1993, the European Space Agency (ESA) suggested ...
Design and implementation of an SDR-based multi-frequency ground-based SAR system
Synthetic Aperture Radar (SAR) has proven a valuable tool in the monitoring of the Earth, either at a global or local scales. SAR is a coherent radar system able to image extended areas with high resolution, and finds ...
DSP-based CW lidars for clouds and aerosol
This thesis aims at exploring the limits of low peak-power, low-cost, all-semiconductor, compact lidars (laser radars) for range-resolved remote sensing of atmospheric aerosols and clouds. The systems investigated are based ...
Parallel scalability of face detection in heterogeneous multithreaded architectures
Recently, facial recognition systems have become extremely popular and deployments of this technology are now ubiquitous. Applications ranging from access control to automated surveillance of video feeds rely on facial ...
Advanced signal processing techniques for robust state estimation applications in smart grids
Since their inception, more than one century ago, electrical grids have played the role of a critical infrastructure. During the majority of this time, power systems have not faced radical changes. In contrast, over the ...
Learning to extract features for 2D – 3D multimodal registration
The ability to capture depth information form an scene has greatly increased in the recent years. 3D sensors, traditionally high cost and low resolution sensors, are being democratized and 3D scans of indoor and outdoor ...
Spatial modulation schemes and modem architectures for millimeter wave radio systems
The rapid growth of wireless industry opens the door to several use cases such as internet of things and device-to-device communications, which require boosting the reliability and the spectral efficiency of the wireless ...
Resource optimization in SDN-based inter/intra data centre networks
Upon the demanding requirements brought by next-generation services, current network infrastructures are required to evolve in the way they manage different types of resources at the data layer. To this end, a set of novel ...
Advanced GNSS-R instruments for altimetric and scatterometric applications
This work is the result of more than eight years during a bachelor thesis, a master thesis, and the Ph.D. thesis dedicated to the development of the Microwave Interferometric Reflectometer (MIR) instrument. It summarizes ...
Radio resource management for V2X in cellular systems
The thesis focuses on the provision of cellular vehicle-to-everything (V2X) communications, which have attracted great interest for 5G due to the potential of improving traffic safety and enabling new services related to ...
Design and optimization of metro-access networks supporting 5G services
The Internet data traffic constant growth caused by the popularization of cloud services, mobile and social networks, demand changes to the networks in order to enable scalable growth in traffic volume, while supporting a ...
Polar coding for the wiretap broadcast channel
In the next era of communications, where heterogeneous, asynchronous and ultra-low latency networks are drawn on the horizon, classical cryptography might be inadequate due to the excessive cost of maintaining a public-key ...
