Minimum error entropy estimation under contaminated Gaussian noise
(Institute of Electrical and Electronics Engineers (IEEE), 2023-10-12)
Article
Accés obertIt is shown that Rényi's entropy of a Gaussian mixture with entropic index α∈(1,∞] is upper-bounded by the cluster with minimum variance. This basic idea leads to a clean worst-case formulation of the minimum error entropy ... -
Subspace leakage in conventional and dimensionally spread null-space communications
(2023-10)
Article
Accés obertThis letter evaluates the impact of subspace leakage in conventional (single-dimension) and dimensionally spread null-space precoding schemes. This phenomenon arises when the null-space inference procedure lacks precision ... -
Prediction models using artificial intelligence and longitudinal data from electronic health records: a systematic methodological review
(2023-12)
Article
Accés obertObjective: To describe and appraise the use of artificial intelligence (AI) techniques that can cope with longitudinal data from electronic health records (EHRs) to predict health-related outcomes. Methods: This ... -
Optimizing access demand for mMTC traffic using neural networks
(Institute of Electrical and Electronics Engineers (IEEE), 2023-12)
Article
Accés obertMachine-type communications show unique spatial and temporal correlation properties that often lead to bursty access demand profiles. With the expected large-scale deployment of the Internet of Things (IoT), next-generation ... -
Multiqubit time-varying quantum channels for NISQ-era superconducting quantum processors
(American Physical Society, 2023-07)
Article
Accés obertTime-varying quantum channels (TVQCs) have been proposed as a model to include fluctuations of the relaxation (T1) and dephasing times (T2). In previous works, realizations of multiqubit TVQCs have been assumed to be equal ... -
Contribution of frailty to multimorbidity patterns and trajectories: Longitudinal dynamic cohort study of aging people
(2023-06-27)
Article
Accés obertBackground: Multimorbidity and frailty are characteristics of aging that need individualized evaluation, and there is a 2-way causal relationship between them. Thus, considering frailty in analyses of multimorbidity is ... -
On the estimation of Tsallis entropy and a novel information measure based on its properties
(2023-06-30)
Article
Accés obertThis letter explores a plug-in estimator of second-order Tsallis entropy based on Kernel Density Estimation (KDE) and its implicit regularization process. First, it is shown that the expected value of the estimator corresponds ... -
Context-aware lossless and lossy compression of radio frequency signals
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-03-28)
Article
Accés obertWe propose an algorithm based on linear prediction that can perform both the lossless and near-lossless compression of RF signals. The proposed algorithm is coupled with two signal detection methods to determine the presence ... -
Regularized estimation of information via canonical correlation analysis on a finite-dimensional feature space
(2023-08)
Article
Accés obertThis paper aims to estimate the information between two random phenomena by using consolidated second-order statistics tools. The squared-loss mutual information, a surrogate of the Shannon mutual information, is chosen ... -
Interference mitigation in feedforward opportunistic communications
(2023-05)
Article
Accés obertThis paper deals with scenario-aware, uncoordinated, and distributed signaling techniques in the context of feedforward opportunistic communications, that is, when the opportunistic transmitting node does not cooperate ... -
Rate optimization for RIS-aided mMTC networks in the finite blocklength regime
(2023-03)
Article
Accés obertReconfigurable intelligent surfaces (RISs) have become a promising candidate for the development of future mobile systems. In the context of massive machine-type communications (mMTC), a RIS can be used to support the ... -
Perfect and quasi-perfect codes for the Bosonic classical-quantum channel
(2023-01-18)
Article
Accés obertWe explore perfect and quasi-perfect codes for the Bosonic channel, where information is generated by a laser and conveyed in the form of coherent states. In particular, we consider the phase-modulation codebook for coherent ...
