On the coordination of base stations in ultra dense cellular networks
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Open AccessUltra dense networks (UDNs) allow for efficient spatial reuse of the spectrum, giving rise to substantial capacity and power gains. However, recent findings have demonstrated that the reduction of inter-site distances after ... -
Polar coding for common message only wiretap broadcast channel
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyA polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send a private and a confidential message that ... -
Publicness, privacy and confidentiality in the single-serving quantum broadcast channel
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference lecture
Restricted access - publisher's policyThe 2-receiver broadcast channel with primary and third-party receivers is studied. The messages are classified into public, private and confidential. The messages in the public class are messages intended for both receivers. ... -
Positioning and timing in the MIMO-gnss framework
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Restricted access - publisher's policyThis paper discusses about GNSS-based positioning and timing in challenging propagation conditions for receivers featuring an array of antennas with an arbitrary distribution. In particular, the positioning and timing ... -
Interference statistics approximations for data rate analysis in uplink massive MTC
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Restricted access - publisher's policyMachine-type-communications have attracted a lot of interest in the past years. They rely on interactions between devices with no human supervision. This will help to the advent of a plethora of applications such as the ... -
Improved modelling of ionospheric disturbances for remote sensing and navigation
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Restricted access - publisher's policyA generic software tool to evaluate the impact of ionospheric disturbances is presented, including low and high latitude physically-based models, and low and high frequency fluctuations. This tool has been developed ... -
One-shot capacity bounds on the simultaneous transmission of public and private information over quantum channels
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Restricted access - publisher's policyWe aim to study the optimal rates of transmission of public and private classical information over a quantum channel in the most general channel model. To this end, we discuss a scenario in which a quantum channel is being ... -

Conference report
Open AccessEn este trabajo se presenta tanto el diseño como la experimentación de un Laboratorio Virtual de Comunicaciones Analógicas y Digitales: LaViCAD. Mediante LaViCAD se pueden experimentar y verificar diferentes aplicaciones ... -
Modeling and control of a three-phaseg grid-connected inverter under fault conditions
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThe aim of this paper is to study the behavior of a three-phase inverter with an RL filter powered by a renewable energy source and connected to a grid under fault conditions. The novelty of the work lies in proposing a ... -
A practical approach for NLOS mitigation in location-aware networks
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThis paper introduces a practical two-stage approach to achieve the mitigation of the Non Line Of Sight condition by using space-time diversity in timing-based mobile subscribers positioning systems. The first stage performs ... -
Uncoordinated space-frequency pilot design for multi-antenna wideband opportunistic communications
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThe statistical side information of interference channels is exploited in this paper to derive a novel uncoordinated on-line pilot design strategy for opportunistic communications. Assuming a time division duplex (TDD), ... -
Receive antenna selection and hybrid precoding for receive spatial modulation in massive MIMO systems
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Open AccessRecently, a receive spatial modulation (RSM) for massive multiple-input-multiple-output operating in millimeter wave (mmWave) was introduced with the purpose of simplifying user terminal circuit by employing only one ...
