Energy driven transmission schemes for coexistence between HTC and MTC
(VDE Verlag, 2021)
Conference report
Restricted access - publisher's policyCoexistence between human-type and machine-type communications is essential in future cellular networks. The former demands high data rates whereas long battery lifetimes are crucial for the latter. In this paper, we ... -
Hierarchical beamforming in random access channels
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference lecture
Open AccessManaging a massive number of terminals in a contention-based multiple access is challenging due to its intrinsic limited efficiency. For example, in the random access channel considered in LTE-A and 5G NR, Base Station ... -
A multi-armed bandit model for non-stationary wireless network selection
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessThe amount of wireless networks and technologies such as 5G have been rapidly increasing in the last years. With this growth in number it has become more relevant to be able to select the best network with the goal of ... -
Correlated binary data for machine learning
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessData sets containing instances that are assigned values by an ensemble of annotators of unknown accuracy are becoming increasingly common. Binary, potentially correlated data are frequent in a number of disciplines, and ... -
Affine projection subspace tracking
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference lecture
Open AccessIn this paper, we consider the problem of estimating and tracking an R-dimensional subspace with relevant information embedded in an N-dimensional ambient space, given that N>>R. We focus on a formulation of the signal ... -
Variance processing for stable boundary-layer height estimation using backscatter lidar data: A discussion
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessIn this paper we present a method for estimating the height of the nocturnal stable boundary layer by using lidar measurements and a single radiosonde for unambiguous initial guess. The method relies on the correlation ... -
Floating Doppler Wind Lidar motion simulator for horizontal wind speed measurement error assessment
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessThis study presents a wind retrieval simulator of a floating Doppler Wind Lidar (DWL) with 6 Degrees of Freedom (DoF) motion. The simulator considers a continuous-wave conical-scanning floating DWL which retrieves the wind ... -
Realistic beamforming design using SRS-based channel estimate for ns-3 5G-LENA module
(Association for Computing Machinery (ACM), 2021)
Conference report
Restricted access - publisher's policyBeamforming (BF) is a key procedure to overcome propagation limits in millimeter-wave bands but also to extend network coverage in sub 6 GHz bands, as considered in recent 3GPP and IEEE communication standards. Up to date, ... -
Novel radio environment map for the ns-3 NR simulator
(Association for Computing Machinery (ACM), 2021)
Conference report
Restricted access - publisher's policyRadio Environmental Map (REM) is a useful tool to visualize the network coverage, including signal quality and interference, in multi-cell scenarios. Although REM maps for omnidirectional transmissions/receptions and tools ... -
An IR-HARQ scheme for covert communications
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessThis paper explores the advantages of incremental redundancy hybrid-ARQ schemes for covert communications in which a feedback channel is available. The use of efficient incremental redundancy with sub-codewords of different ... -
Energy-efficient analog beamforming with short packets in millimeter-wave MIMO systems
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThe energy-aware design of fully analog precoders and combiners is investigated in this paper. To that aim, we consider a millimeter-wave short-packet communication scenario where power consumption and hardware complexity ... -
Rate allocation in massive multiple access combining successive decoding with error control
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessThe Gaussian multiple access channel under asymptotically many code-division-multiple-access users and successive interference cancellation (SIC) is investigated in this work. Users transmit n-symbol packets and select ...
