A novel methodology for adaptive community detection
(Universitat Politècnica de Catalunya, 2019-06)
Bachelor thesis
Open AccessCommunity detection and statistical dependence detection between different sets of data are two very intertwined topics of research with many real world applications in areas involving information science resources, such ... -
Bootstrap signal processing: doing the impossible?
(Universitat Politècnica de Catalunya, 2018-06)
Bachelor thesis
Open AccessClassical signal processing techniques are developed under prior statistical knowledge of the kind of data we are processing. Unfortunately, one does not know too much about reality in practice, therefore inferring information ... -
Contributions to anomaly detection and correction in co-evolving data streams via subspace learning
(Universitat Politècnica de Catalunya, 2020-07)
Master thesis
Open AccessDuring decades, estimation and detection tasks in many Signal Processing and Communications applications have been significantly improved by using subspace and component-based techniques. More recently, subspace methods ... -
Data Assimilation under Affine Projection Algorithm
(Universitat Politècnica de Catalunya, 2022-07-05)
Bachelor thesis
Restricted access - confidentiality agreementData assimilation consists of combining multiple sources of information in order to estimate the true state of a physical system as it evolves over time. As this field has multiple applications in today's technology such ... -
Detection of dependence based on kernel signal processing
(Universitat Politècnica de Catalunya, 2017-02)
Master thesis
Open Access -
Discovering causality
(Universitat Politècnica de Catalunya, 2018-05)
Bachelor thesis
Open AccessThis thesis aims to study the field of signal processing applied to the detection of common causes in processes apparently from different origins. This will be done using adaptive filtering, more specifically three different ... -

(Universitat Politècnica de Catalunya, 2015-05-29)
Master thesis (pre-Bologna period)
Restricted access - confidentiality agreement -
Implementation of FAPEC decorrelation stages for IQ and water column data
(Universitat Politècnica de Catalunya, 2021-07-08)
Bachelor thesis
Open AccessRecent technological advances have resulted in massive data collection, also in hazard environments such as the sea or space. In these situations, both computing power and downlink bandwidth are quite limited. For this ... -
Lens antenna arrays: an efficient framework for sparse-aware large-MIMO communications
(Universitat Politècnica de Catalunya, 2021-06)
Master thesis
Open AccessThe recent increase in the demand for higher data transmission rates in wireless communications has entailed many implementation issues that can only be resolved by going through a full paradigm shift. Making use of the ... -
Millora de l'eficiència espectral de sistemes MIMO massius amb freqüència extremadament alta i coneixement parcial de l'estat del canal
(Universitat Politècnica de Catalunya, 2021-06)
Bachelor thesis
Open AccessSimulation of a new estimation algorithm of channel's correlation for massive MIMO with mmWave and FDD. -
Mitigation of phase disturbances in precise navigation by dynamic programing
(Universitat Politècnica de Catalunya, 2020-09)
Master thesis
Open AccessThe use of carrier phase observations, instead of the code or pseudo-range, is a fundamental strategy that yields millimetre precision in positioning. This carrier phase observation is the measured spatial distance between ... -
Multiuser Random Beamforming in Millimeter-Wave Channels
(Universitat Politècnica de Catalunya, 2019-09)
Master thesis
Open AccessCellular communications exploiting the mmWaves frequency range are com- ing within our technological reach. However the specificities of propagation at these frequencies calls for new transmission schemes. Concerning the ... -
Opportunistic communications using software defined radio
(Universitat Politècnica de Catalunya, 2017-01-26)
Bachelor thesis
Open AccessThe increasing scarcity in the available spectrum is limiting the growth of high bandwidth applications. By exploiting licensed channels when they are unused, Opportunistic Communications aim to use the spectrum in a more ... -
Pilot contamination reduction in massive MIMO systems
(Universitat Politècnica de Catalunya, 2017)
Master thesis
Open Access
Covenantee: Technische Universität MünchenMassive MIMO systems have been pointed out as one of the possible strategies to enhance system performance and reach the high data rates modern wireless communications demand. It represents a breakthrough in modern ... -
Rényi divergence and kernel methods for testing Gaussianity
(Universitat Politècnica de Catalunya, 2022-07-12)
Master thesis
Restricted access - confidentiality agreementGaussianity tests have been used for decades in statistics to determine if a dataset is well modeled by a normal distribution. More recently, they have also found their place in machine learning. The reason of this ... -
Signal Processing for the Ionosphere
(Universitat Politècnica de Catalunya, 2018-01)
Bachelor thesis
Open AccessThis is a pure signal-processing project that is focused on minimize as much as possible the effects caused by the ionosphere over the carrier phases of signals emitted by GPS satellites. These effects are highly related ...
