    Energy efficient spatial modulation-aided uplink and downlink designs for future millimeterwave (mmWave) large-scale multiple-input multiple-output (MIMO) systems are considered. Two novel uplink transceivers are proposed ...
  • Wideband receive spatial modulation with time domain pre-equalizer for large MIMO systems 

    Raafat Hosny Mohamed Fahm, Ahmed; Agustín de Dios, Adrián; Vidal Manzano, José (2018)
    Conference report
    Open Access
    Receive spatial modulation (RSM) schemes are promising for massive multiple-input-multiple-output (MIMO) systems at millimeter wave (mmWave) bands because they require reduced complexity and low consumption hardware at the ...
  • Channel-aware energy allocation for throughput maximization in massive low-rate multiple access 

    Molina Oliveras, Francesc; Sala Álvarez, José; Rey Micolau, Francesc; Villares Piera, Nemesio Javier (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report

    A multiple access (MA) optimization technique for massive low-rate direct-sequence spread spectrum communications is analyzed in this work. A dense network of users transmitting at the same rate to a common central node ...
  • A proof of de Bruijn identity based on generalized Price’s theorem 

    Riba Sagarra, Jaume; Cabrera Estanyol, Ferran de (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture

    This paper shows that de Bruijn identity, which relates entropy with Fisher information, can be obtained as a particular case of an immediate generalization of Price’s theorem, which is a tool used in the analysis of ...
  • Multi-satellite cycle-slip detection and exclusion using the noise subspace of residual dynamics 

    Riba Sagarra, Jaume; Cabrera Estanyol, Ferran de; Juan Zornoza, José Miguel (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    Real-time detection of cycle-slips on undifferenced carrier-phase measurements is an important task to properly exclude wrong phase trackers from precise positioning algorithms. The detection is especially challenging in ...
  • On the coordination of base stations in ultra dense cellular networks 

    Aravanis, Alexios; Muñoz Medina, Olga; Pascual Iserte, Antonio; di Renzo, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Open Access
    Ultra dense networks (UDNs) allow for efficient spatial reuse of the spectrum, giving rise to substantial capacity and power gains. However, recent findings have demonstrated that the reduction of inter-site distances after ...
  • Polar coding for common message only wiretap broadcast channel 

    Olmo Alòs, Jaume del; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Restricted access - publisher's policy
    A polar coding scheme is proposed for the Wiretap Broadcast Channel with two legitimate receivers and one eavesdropper. We consider a model in which the transmitter wishes to send a private and a confidential message that ...
  • Publicness, privacy and confidentiality in the single-serving quantum broadcast channel 

    Salek Shishavan, Farzin; Hsieh, Min-Hsiu; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference lecture
    Restricted access - publisher's policy
    The 2-receiver broadcast channel with primary and third-party receivers is studied. The messages are classified into public, private and confidential. The messages in the public class are messages intended for both receivers. ...
  • Positioning and timing in the MIMO-gnss framework 

    García Molina, J. A.; Fernández Rubio, Juan Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2019)
    Conference report
    Restricted access - publisher's policy
    This paper discusses about GNSS-based positioning and timing in challenging propagation conditions for receivers featuring an array of antennas with an arbitrary distribution. In particular, the positioning and timing ...
