Análisis del comportamiento de esquemas de modulación adaptativos en LTE
Torres Landívar, Víctor
; Esparza Alfaro, Fermín ; Falcone Lanas, Francisco Javier 
(2009)
Contribución a congreso / Biltzarrerako ekarpena 
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 ... -
Evalución de dosimetría de campos electromagnéticos en el entorno interior doméstico
Esparza Alfaro, Fermín; Carranza, Noemí; Torres Landívar, Víctor ; Falcone Lanas, Francisco Javier ; Ramos González, Victoria (2009)
Contribución a congreso / Biltzarrerako ekarpena
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 ... -
Low-power class-AB CMOS voltage feedback current operational amplifier with tunable gain and bandwidth
Esparza Alfaro, Fermín; Pennisi, Salvatore; Palumbo, Gaetano; López Martín, Antonio (IEEE, 2014)
Artículo / Artikulua
A CMOS class AB variable gain Voltage Feedback Current Operational Amplifier (VFCOA) is presented. The implementation is based on class AB second generation current conveyors and exploits an electronically tunable ... -
Power-efficient current-mode analog circuits for highly integrated ultra low power wireless transceivers
Esparza Alfaro, Fermín (2014)
Tesis doctoral / Doktoretza tesia
In this thesis, current-mode low-voltage and low-power techniques have been applied to implement novel analog circuits for zero-IF receiver backend design, focusing on amplification, filtering and detection stages. The ...
