  • The K-filter: a new architecture to model and design non-linear systems from Kolmogorov's theorem 

    Pagès Zamora, Alba Maria; Lagunas Hernandez, Miguel A.; Nájar Martón, Montserrat; Pérez Neira, Ana Isabel (1995-07)
    Article
    Open Access
    A new architecture to model and design nonlinear transfer functions is presented using a new formulation for nonlinear systems. This approach follows the guidelines of the mapping theorem due to A. Kolmogorov and it is ...
  • Robust non-linear precoding for downlink multiuser multiple-input multiple-output orthogonal frequency-division multiplexing systems with limited feedback 

    Font Segura, Josep; Su, Y.; Wang, Xiaodong (2012-08-14)
    Article
    Restricted access - publisher's policy
    The authors consider the robust Tomlinson–Harashima precoding (THP) for downlink multiuser multiple-input multiple-output orthogonal frequency-division multiplexing systems with quantised feedback. The authors discuss ...
  • A diffusion-based em algorithm for distributed estimation in unreliable sensor networks 

    Silva Pereira, Silvana; López Valcarce, Roberto; Pagès Zamora, Alba Maria (2013-01)
    Article
    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 ...
  • Network-MIMO for downlink in-band relay transmissions 

    Lagén Morancho, Sandra; Agustín de Dios, Adrián; Vidal Manzano, José (2013-01-23)
    Article

    With the objective of improving the spectral efficiency and coverage homogeneity of wireless cellular systems in the downlink, we investigate how to take advantage of two promising transmission technologies envisioned in ...
  • Demand-side management via distributed energy generation and storage optimization 

    Atzeni, Italo; García Ordoñez, Luis; Scutari, Gesualdo; Palomar, Daniel P.; Rodríguez Fonollosa, Javier (Institute of Electrical and Electronics Engineers (IEEE), 2013-06)
    Article
    Restricted access - publisher's policy
    Demand-side management, together with the integration of distributed energy generation and storage, are considered increasingly essential elements for implementing the smart grid concept and balancing massive energy ...
  • Noncooperative and cooperative optimization of distributed energy generation and storage in the demand-side of the smart grid 

    Atzeni, Italo; García Ordoñez, Luis; Scutari, Gesualdo; Palomar, Daniel P.; Rodríguez Fonollosa, Javier (2013-05)
    Article
    Restricted access - publisher's policy
    The electric energy distribution infrastructure is undergoing a startling technological evolution with the development of the smart grid concept, which allows more interaction between the supply-and the demand-side of the ...
  • Interference management in LTE-based HetNets: a practical approach 

    Font Bach, Oriol; Bartzoudis, Nikolaos; Pascual Iserte, Antonio; Payaró Llisterri, Miquel; Blanco, Luis; López Bueno, David; Molina Pena, Marc (Wiley-Blackwell, 2015)
    Article
    Open Access
    Interference is a major obstacle in radio communications, especially when opportunistic frequency reuse is an inherent requirement for maximising spectral ef¿ciency in heterogeneous networks. A typical example is encountered ...
  • Coexisting linear and widely linear transceivers in the MIMO interference 

    Lagén Morancho, Sandra; Agustín de Dios, Adrián; Vidal Manzano, José (2016-01)
    Article
    Open Access
    Recent results have shown the benefits of widely linear precoding (WLP) in the MIMO interference channel (MIMO IC) assuming that all transmitters can follow the same strategy. Motivated by a transitional scenario where ...
  • Correlated multiple antennas spectrum sensing under calibration uncertainty 

    Pourgharehkhan, Zahra; Taherpour, Abbas; Sala Álvarez, José; Khattab, Tamer (2015-12-01)
    Article
    Open Access
    We address the problem of spectrum sensing in cognitive radios (CRs) when the secondary user (SU) is equipped with a multiantenna receiver. We consider scenarios with correlation between the received channels at different ...
  • Decentralized coordinated precoding for dense TDD small cell networks 

    Lagén Morancho, Sandra; Agustín de Dios, Adrián; Vidal Manzano, José (2015-08-01)
    Article
    Open Access
    Cellular networks need the densification of small eNBs (SeNBs) to face the tremendous data traffic demand growth, implying an interference increase and making transmit coordination a key enabler. This article proposes a ...
