Enhanced Time-Modulated Arrays for Harmonic Beamforming
(Institute of Electrical and Electronics Engineers, 2017)[Abstract]: One of the primary features of time-modulated arrays (TMAs) is their ability to adapt their harmonic patterns to exploit the angular diversity of multipath wireless channels. In such a case, the TMA excitations ... -
Environmental Cross-Validation of NLOS Machine Learning Classification/Mitigation with Low-Cost UWB Positioning Systems
(M D P I AG, 2019-12-10)[Abstract] Indoor positioning systems based on radio frequency inherently present multipath-related phenomena. This causes ranging systems such as ultra-wideband (UWB) to lose accuracy when detecting secondary propagation ... -
Equalizers in mobile communications: Tutorial 38
(Institute of Electrical and Electronics Engineers & Instrumentation and Measurement Society, 2012-06)[Abstract]: Modern cellular wireless systems would not be possible without high-performance equalizers. Signal impairments introduced by the wireless channel can only be compensated for by using such equalizers. This ... -
Estimation of Laplacian Symbols for Analog Transmission Over MIMO Channels
(Institute of Electrical and Electronics Engineers, 2015-12)[Abstract]: The MAP and MMSE estimation of Laplace-distributed symbols transmitted over multiple-input multiple-output channels is studied. This is an important problem in analog joint source channel coding with spiral ... -
Evaluation of Analog Joint Source-Channel Coding Systems for Multiple Access Channels
(Institute of Electrical and Electronics Engineers, 2015-06)[Abstract]: We address the evaluation of low-complexity analog Joint Source Channel Coding (JSCC) methods for the transmission of discrete-time analog symbols over Multiple-Input Multiple-Output (MIMO) Multiple Access ... -
Evaluation of H.264/AVC over IEEE 802.11p vehicular networks
(SpringerOpen & European Association for Signal Processing, 2013)[Abstract]: The capacity of vehicular networks to offer non-safety services, like infotainment applications or the exchange of multimedia information between vehicles, have attracted a great deal of attention to the field ... -
Una experiencia de aprendizaje basado en proyectos en Ingeniería Informática
