  • Polar coding for the wiretap broadcast channel with multiple messages 

    Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference lecture
    Open Access
    A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eaves-dropper. We consider a model in which the transmitter wishes to to reliably send different confidential and ...
  • Stochastic geometry analysis and design of wireless powered MTC networks 

    Liesegang Maria, Sergi; Muñoz Medina, Olga; Pascual Iserte, Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    Machine-type-communications (MTC) are being crucial in the development of next generation mobile networks. Given that MTC devices are usually battery constrained, wireless power transfer (WPT) and energy harvesting (EH) ...
  • Autoencoders for health improvement by compressing the set of patient features 

    Cabrera-Bean, Margarita; Pereira Dos Santos, Víctor Jerri; Roso Llorach, Albert; Fernández Bertolín, Sergio; Vidal Manzano, José; Violán Fors, Concepción (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference lecture

    A challenge to solve when analyzing multimorbidity patterns in elderly people is the management of a high number of characteristics associated with each patient. The main variables to study multimorbidity are diseases, ...
  • Array-geometry invariant signaling for MISO feedforward opportunistic communications 

    Borràs Pino, Jordi; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    The impact of antenna array geometry on scenario- aware invariant signaling is studied in the context of feedforward opportunistic communications. Invariance plays an elemental role to guarantee the detectability in ...
  • Energy allocation for short-packet massive multiple access with two-iteration successive decoding 

    Molina Oliveras, Francesc; Sala Álvarez, José (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    An optimum energy allocation for massive user networks operating under iterative successive interference cancellation (I-SIC) is derived in this work. We analyze an uplink setting where a large network of cost-effective ...
  • Source enumeration via Toeplitz matrix completion 

    Vaibhav, Garg; Giménez Febrer, Pedro Juan; Pagès Zamora, Alba Maria; Santamaria Caballero, Ignacio (Institute of Electrical and Electronics Engineers (IEEE), 2020)
    Conference report
    Open Access
    This paper addresses the problem of source enumeration by an array of sensors in the presence of noise whose spatial covariance structure is a diagonal matrix with possibly different variances, referred to non-iid noise ...
  • A novel formulation of independence detection based on the sample characteristic function 

    Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference lecture
    Open Access
    A novel independence test for continuous random sequences is proposed in this paper. The test is based on seeking for coherence in a particular fixed-dimension feature space based on a uniform sampling of the sample ...
  • Squared-loss mutual information via high-dimension coherence matrix estimation 

    Cabrera Estanyol, Ferran de; Riba Sagarra, Jaume (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Open Access
    Squared-loss mutual information (SMI) is a surro- gate of Shannon mutual information that is more advantageous for estimation. On the other hand, the coherence matrix of a pair of random vectors, a power-normalized version ...
  • Interference mitigation under degrees-of-freedom sensing uncertainties in opportunistic transmission 

    Borràs Pino, Jordi; Vázquez Grau, Gregorio (2019)
    Conference report
    Open Access
    Inter-system interference may limit the performance of co-existing systems in dense heterogeneous wireless networks. Context-aware waveform design can profitably overcome this limitation. However, the latter substantially ...
  • A non-linear channel code for covert communications 

    Lamarca Orozco, M. Meritxell; Matas Navarro, David (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Restricted access - publisher's policy
    This paper presents an explicit channel code design for covert communications in the Binary Symmetric Channel. The proposed architecture is composed of the serial concatenation of a linear code and a graph-based non-linear ...
  • Joint energy and rate allocation for successive interference cancellation in the finite blocklength regime 

    Molina Oliveras, Francesc; Sala Álvarez, José; Villares Piera, Nemesio Javier; Rey Micolau, Francesc (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference lecture
    Open Access
    This work addresses the optimization of the network spectral efficiency (SE) under successive interference cancellation (SIC) at a given blocklength n. We adopt a proof-of-concept satellite scenario where network users can ...
  • Decentralized shaping for pilot generation and detection in opportunistic communications 

    Borràs Pino, Jordi; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    The uncoordinated design of pulse shaping filters for opportunistic communications is addressed. We show that under degrees-of-freedom sensing uncertainties the waveform design problem can be cast as a minimum-norm ...
