    This paper discusses the unambiguous estimation of high-order BOC signals in the cloud based on signal snapshots gathered by low-end SDR receivers. In particular, the sensitivity and distortion problems are introduced, ...
  • Receive spatial modulation for massive MIMO systems 

    Raafat, Ahmed; Agustín de Dios, Adrián; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2017)
    Text en actes de congrés
    Accés obert
    In this paper, we consider the downlink of a massive multiple-input-multiple-output (MIMO) single user transmission system operating in the millimeter wave outdoor narrowband channel environment. We propose a novel receive ...
  • Signal-timing offset compensation in dense TDD OFDM-based networks 

    Agustín de Dios, Adrián; Lagén Morancho, Sandra; Vidal Manzano, José (Institute of Electrical and Electronics Engineers (IEEE), 2017)

    Interference may pose a severe limitation to massive wireless multiple access unless the central receiver is endowed with strong multipacket reception capabilities. In that respect, Interference Cancellation (IC) has been ...
  • Assessment of RSS model calibration with real WLAN devices 

    Castro, Juan Manuel; Moragrega, Ana; Closas, Pau; Fernández Rubio, Juan Antonio (2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Received Signal Strength (RSS) for indoor 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. This ...
