Radio resource management techniques for QoS provision in 5G networks
(Universitat Politècnica de Catalunya, 2018-11-26)
Tesi
Accés obertAs numerous mobile applications and over-the-top (OTT) services emerge and mobile Internet connectivity becomes ubiquitous, the provision of high quality of service (QoS) is more challenging for mobile network operators ... -
Radio frequency interference detection and mitigation techniques for navigation and Earth observation
(Universitat Politècnica de Catalunya, 2018-11-09)
Tesi
Accés obertRadio-Frequency Interference (RFI) signals are undesired signals that degrade or disrupt the performance of a wireless receiver. RFI signals can be troublesome for any receiver, but they are especially threatening for ... -
Applications of L-band missions for environmental research
(Universitat Politècnica de Catalunya, 2018-10-15)
Tesi
Accés obertHuman activity leads to environmental changes which threaten the vegetation. Global warm ing trends, deforestation and land cover, or modified Earth's surface albedo, are sorne examples of these environmental changes. ... -
Semantic and generic object segmentation for scene analysis using RGB-D Data
(Universitat Politècnica de Catalunya, 2018-07-20)
Tesi
Accés obertIn this thesis, we study RGB-D based segmentation problems from different perspectives in terms of the input data. Apart from the basic photometric and geometric information contained in the RGB-D data, also semantic and ... -
Cellular networks for smart grid communication
(Universitat Politècnica de Catalunya, 2018-07-19)
Tesi
Accés obertThe next-generation electric power system, known as smart grid, relies on a robust and reliable underlying communication infrastructure to improve the efficiency of electricity distribution. Cellular networks, e.g., LTE/LTE-A ... -
Deep learning for i-vector speaker and language recognition
(Universitat Politècnica de Catalunya, 2018-05-29)
Tesi
Accés obertOver the last few years, i-vectors have been the state-of-the-art technique in speaker and language recognition. Recent advances in Deep Learning (DL) technology have improved the quality of i-vectors but the DL techniques ... -
Investigation of continuous-wave range-resolved lidar systems for gas detection and concentration measurement
(Universitat Politècnica de Catalunya, 2011-07-27)
Tesi
Accés obertThe techniques for detection of the atmosphere constituents and their distribution in the space have evolved in the last years driven by needs in the environmental, meteorological and climate science fields and backed by ... -
