Effect of electron number densities on the radio signal propagation in an inductively coupled plasma facility
(2023-11)
Article
Accés obertSpacecraft entering a planetary atmosphere are surrounded by a plasma layer containing high levels of ionization, due to the extreme temperatures in the shock layer. The high electron number densities cause attenuation of ... -
Generating indoor scenarios for wireless communications
(Universitat Politècnica de Catalunya, 2016-07-29)
Treball Final de Grau
Accés obert
Realitzat a/amb: Technische Universität WienThis research focuses on creating a realistic situation for wireless communications in indoor scenarios, in order to study the behaviour of its signal propagation. The main purpose of this project consists in creating an ... -
Herramienta para el procesado de campañas de medidas y ajuste de modelos de propagación
(Universitat Politècnica de Catalunya, 2012-05-07)
Treball Final de Grau
Accés restringit per decisió de l'autorPara poder implementar un sistema de comunicaciones inalámbrico, los operadores necesitan evaluar cómo se caracteriza la propagación a través del canal radio. Esto permite conocer el impacto de las pérdidas sobre el servicio ... -
Ionospheric scintillation model limitations and impact in GNSS-R missions
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Text en actes de congrés
Accés obertThe ionosphere impacts radio-wave propagation, notably up to a few GHz. The main applications impacted by the ionosphere are GNSS positioning and timing, Earth Observations (especially low frequency SAR missions e.g. ... -
Ionospheric signal propagation simulator for earth observation missions
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés obertFollowing the discovery of the ionosphere by Marconi in 1901, different disciplines have been influenced from the ionospheric effects on radio-waves, such as communications or Earth Observation missions. The ionosphere ... -
On the testing of the magnetic field integral equation with RWG basis functions in method of moments
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-11-30)
Article
Accés obertFor electromagnetic analysis using method of moments (MoM), three-dimensional (3-D) arbitrary conducting surfaces are often discretized in Rao, Wilton and Glisson basis functions. The MoM Galerkin discretization of the ... -
Performance of 16 & 64 QAM digital radio systems with multipath propagation and distortion induced phase jitter
(Institute of Electrical and Electronics Engineers (IEEE), 1989)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper presents a new method for assessing the bit error probability in a QAM system taking into account thermal noise, multipath distortion and phase Jitter. System signature is calculated for a system without any ... -

Reconfigurable pixel-layer isolator for frequency-tunable on-frequency repeaters
(2014)
Article
Accés restringit per política de l'editorialThe maximum gain in on-frequency repeaters is limited by the isolation level between their two antennas due to close-loop stability conditions. In this letter, a novel pixel-layer isolator for tunable on-frequency repeaters ... -
