(2020-10-01)En este trabajo, se presentan varios métodos para planificar la asignación de celdas a unidades de procesado en banda base en una red de acceso radio centralizada que incluye macroceldas y celdas pequeñas de interior. El ... -
Assessing Functional Brain Network Dynamics in Dyslexia From fNIRS Data
(World Scientific, 2023-01-09)Developmental dyslexia is characterized by a deficit of phonological awareness whose origin is related to atypical neural processing of speech streams. This can lead to differences in the neural networks that encode audio ... -
Assessing Physical Activity and Functional Fitness Level Using Convolutional Neural Networks.
(Elsevier, 2019-12-01)Older adults are related to a reduction in physical functionality, as a result of a musculoskeletal system degeneration. In that way, physical exercise has been stated as a suitable intervention to prevent such health ... -

Assessment of the impact of limited computing resources on vRAN deployment.
(2023)The new generation of mobile networks goes beyond radio communications by providing a resilient and flexible architecture. In this context, the virtualization of Radio Access Networks (vRAN) completes the Network Function ... -
Asymptotically Exact Approximations for the Symmetric Difference of Generalized Marcum-Q Functions
(IEEE, 2015)In this paper, we derive two simple and asymptotically exact approximations for the function defined as ΔQm(a, b) =Δ Qm(a, b) - Qm(b, a). The generalized Marcum Q-function Qm(a, b) appears in many scenarios in communications ... -
Automatic alarm prioritization by data mining for fault management in cellular networks.
(Elsevier, 2020-05-30)Network management systems play an important role to deal with the large size and complexity of current cellular networks. Thus, operators and vendors focus much of their efforts on developing new techniques and tools for ... -
Automatic design of high-performance fiber-chip surface grating couplers based on Floquet-Bloch mode analysis
(2018-04-30)We propose a new strategy to automatically design highly efficient fiber-chip surface grating couplers. High performance designs are achieved with a substantially reduced computational cost by combining Floquet-Bloch mode ... -
Automatic Extraction of Measurement-Based Large-Signal FET Models by Nonlinear Function Sampling.
(IEEE, 2020-03-27)A new method is proposed for the accurate experimental characterization and fully automated extraction of compact nonlinear models for Field-Effect Transistors (FETs). The approach, which leads to a charge-conservative ... -
Automatic Feature Selection Technique for Next Generation Self-Organizing Networks
(IEEE, 2018)Despite self-organizing networks (SONs) pursue the automation of management tasks in current cellular networks, the selection of the most useful performance indicators (PIs), used as inputs for SON functions, is still ... -
