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 ... -

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 ... -
Closed-form capacity bounds for downlink and uplink decoupling
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Open AccessDownlink (DL) and uplink (UL) decoupling (DUDe) is a new architectural paradigm where DL and UL are not constrained to be associated to the same base station (BS). Thus, a user having access to multiple BSs within a dense ... -
MMSE precoding for receive spatial modulation in large MIMO systems
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Open AccessReceive spatial modulation (RSM) schemes enable simple and energy efficient multiple-input-multiple-output (MIMO) transceivers and yet attain high spectral efficiency, which renders them promising schemes for millimeter ... -
Robust estimation of the magnitude squared coherence based on Kernel signal processing
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference lecture
Restricted access - publisher's policyA new outlier-robust approach to estimate the magnitude squared coherence of a random vector sequence, a common task required in a variety of estimation and detection problems, is proposed. The proposed estimator is based ... -
Dimension spreading for coherent opportunistic communications
(Institute of Electrical and Electronics Engineers (IEEE), 2018)
Conference report
Restricted access - publisher's policyThe waveform optimization problem for opportunistic communications is addressed, based on sensing the second-order statistics of the existing transmissions. We propose a minimum-norm waveform optimization that exhibits ... -
Learning from unequally reliable blind ensembles of classifiers
(Institute of Electrical and Electronics Engineers (IEEE), 2017)
Conference report
Open AccessThe rising interest in pattern recognition and data analytics has spurred the development of a plethora of machine learning algorithms and tools. However, as each algorithm has its strengths and weaknesses, one is motivated ...
