  • Compressed spectrum sensing in the presence of interference: comparison of sparse recovery strategies 

    Lagunas Targarona, Eva; Nájar Martón, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    Existing approaches to Compressive Sensing (CS) of sparse spectrum has thus far assumed models contaminated with noise (either bounded noise or Gaussian with known power). In practical Cognitive Radio (CR) networks, primary ...
  • Decentralized widely linear precoding design for the MIMO interference channel 

    Lagén Morancho, Sandra; Agustín de Dios, Adrián; Vidal Manzano, José (2014)
    Conference report
    Restricted access - publisher's policy
    his paper addresses the interference management in a MIMO interference channel (MIMO-IC) by proposing a decentralized transmit and receive beamformer optimization using improper (or circularly asymmetric complex) Gaussian ...
  • Channel training procedures for MIMO interfering point-to-multipoint channel 

    Agustín de Dios, Adrián; Lagén Morancho, Sandra; Vidal Manzano, José (2014)
    Conference report
    Restricted access - publisher's policy
    A precise knowledge of the MIMO channel between the serving node and the user equipment (UE) is important for attaining good data rates in downlink transmissions (DL) in cellular systems. The interfering point-tomulti ...
  • Joint scheduling of communication and computation resources in multiuser wireless application offloading 

    Molina Pena, Marc; Muñoz Medina, Olga; Pascual Iserte, Antonio; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Open Access
    We consider a system where multiple users are connected to a small cell base station enhanced with computational capabilities. Instead of doing the computation locally at the handset, the users offload the computation ...
  • Subset relay selection in wireless cooperative networks using sparsity-inducing norms 

    Blanco, Luis; Nájar Martón, Montserrat (2014)
    Conference report
    Restricted access - publisher's policy
    This paper addresses the problem of multiple relay selection in a two-hop wireless cooperative network. In particular, the proposed technique selects the best subset of relays, in a distributed beamforming scheme, which ...
  • Spatial sparsity based direct positioning for IR-UWB in IEEE 802.15.4a channels 

    Lagunas Targarona, Eva; Navarro, Mònica; Closas Gómez, Pau; Nájar Martón, Montserrat (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    In this paper, we focus on the application of Compressive Sensing (CS) techniques to Impulse Radio (IR) Ultra-WideBand (UWB) positioning systems under indoor propagation environments. Direct Position Estimation (DPE) ...
  • An architecture for mobile computation offloading on cloud-enabled LTE small cells 

    Lobillo Vilela, Felicia; Becvar, Zdenek; Puente, Miguel Angel; Mach, Pavel; Lo Presti, Francesco; Gambetti, Fabrizio; Goldhamer, Mariana; Vidal Manzano, José; Widiawan, Anggoro K.; Calvanesse, Emilio (Institute of Electrical and Electronics Engineers (IEEE), 2014)

    Small cell networks are currently seen as a new way to satisfy the increasing wireless traffic demand. The proximity of base stations to subscribers brings many possibilities for the development of new applications, including ...
  • A diffusion-based distributed EM algorithm for density estimation in wireless sensor networks 

    Silva Pereira, Silvana; López Valcarce, Roberto; Pagès Zamora, Alba Maria (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Restricted access - publisher's policy
    We address the problem of distributed estimation of a parameter from a set of noisy observations collected by a sensor network, assuming that some sensors may be subject to data failures and report only noise. In such ...
  • Cramér-Rao lower bound for breakpoint distance estimation in a path-loss model 

    Castro Arvizu, Juan Manuel; Closas Gómez, Pau; Fernández Rubio, Juan Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    This paper addresses the problem of determining the Cramér-Rao lower bound (CRLB) for the parameters and breakpoint distance in a Path-Loss Channel model for Received Signal Strength (RSS) measurements. The path loss model ...
  • Energy profiling of FPGA-based PHY-layer building blocks encountered in modern wireless communication systems 

    Bartzoudis, Nikolaos; Font Bach, Oriol; Payaró Llisterri, Miquel; Pascual Iserte, Antonio; Rubio López, Javier; García Fernández, Juan José; García Armada, Ana (2014)
    Conference lecture
    Restricted access - publisher's policy
    Characterizing the energy cost of different physical (PHY) layer building blocks is becoming increasingly important in modern cellular-based communications, considering the cross sector requirements for performance ...
