  • List message passing algorithm for noiseless compressed sensing 

    Ramírez Javega, Francisco; Lamarca Orozco, M. Meritxell (2015)
    Conference report
    Restricted access - publisher's policy
    We propose a verification-based algorithm for noiseless Compressed Sensing that reconstructs the original signal operating on a sparse graph. The proposed scheme has affordable computational complexity and its performance ...
  • Simultaneous tracking and RSS model calibration by robust filtering 

    Castro Arvizu, Juan Manuel; Vila Valls, Jordi; Closas, Pau; Fernández Rubio, Juan Antonio (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report
    Restricted access - publisher's policy
    Received Signal Strength (RSS) localization is widely used due to its simplicity and availability in most mobile devices. The RSS channel model is defined by the propagation losses and the shadow fading. These parameters ...
  • Harvesting management in multiuser MIMO systems with simultaneous wireless information and power transfer 

    Rubio López, Javier; Pascual Iserte, Antonio (2015)
    Conference lecture
    Restricted access - publisher's policy
    In this paper, we focus on a broadcast multiuser multiple-input multiple-output (MIMO) system where we consider that some terminals harvest power and, thus, recharge their batteries through wireless power transfer from the ...
  • Decentralized beamforming with coordinated sounding for inter-cell interference management 

    Lagén Morancho, Sandra; Agustín de Dios, Adrián; Vidal Manzano, José (VDE Conference Publications, 2014)
    Conference report
    Restricted access - publisher's policy
    This paper presents and evaluates a decentralized beamforming design for inter-cell interference management that is highly recommended in Time Division Duplex (TDD) cellular network deployments and interference limited ...
  • 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) ...
