    Análisis del comportamiento de esquemas de modulación adaptativos en LTE
    (2009) Torres Landívar, Víctor; Esparza Alfaro, Fermín; Falcone Lanas, Francisco Javier; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    In this work, the behaviour of several modulation schemes used in 3GPP R8 or Long Term Evolution (LTE) Systems is analyzed. In order to increase the capacity of future mobile networks, high order modulation schemes like 64-QAM are envisaged, which have more stringent Signal-to-Noise restrictions. System simulation results for various modulation schemes regarding Error Vector Magnitude (EVM) values and constellation behaviour are obtained, showing dependence of quality degradation with bit rate, interference ratio and relative constellation position of the symbols. These results, related to constellation behaviour, can aid in the future design of high data rate mobility systems based on LTE.

    Evalución de dosimetría de campos electromagnéticos en el entorno interior doméstico
    (2009) Esparza Alfaro, Fermín; Carranza, Noemí; Torres Landívar, Víctor; Falcone Lanas, Francisco Javier; Ramos González, Victoria; Ingeniería Eléctrica y Electrónica; Ingeniaritza Elektrikoa eta Elektronikoa
    In this work, the evaluation of radiofrequency exposure in a domestic environment is analyzed. 3D raytracing simulation results are compared with dossimetry measurement results in a probe household in a dense urban area in Madrid. The results reveal that a variety of electromagnetic components are present in the household, from mobile communication systems, TV, radio as well as WLAN signals. The results aim to gain insight in the observation and prediction of regulatory compliance as well as in the assessment of possible risk.
