    The waveform optimization problem for opportunistic communications is addressed, based on sensing the second-order statistics of the existing transmissions. We propose a minimum-norm waveform optimization that exhibits ...
  • Noise subspace communication: waveform optimization and interference management 

    Borràs Pino, Jordi (Universitat Politècnica de Catalunya, 2016-07-14)
    Bachelor thesis
    Open Access
    Nowadays, the increasing demand for high data-rate services increases the interest of spectral efficiency. As it is well-known, the spectrum is a limited resource. Thus, those newest techniques should exploit it efficiently. ...
  • Pilot contamination in context-aware pilot-based opportunistic communications 

    Borràs Pino, Jordi (Universitat Politècnica de Catalunya, 2018-07)
    Master thesis
    Restricted access - author's decision
    The increasing demand of high data-rate services and the unstoppable growth of communicating interfaces are two important features of next-era wireless communications. Albeit some strategies have recently arisen to deal ...
  • Uncoordinated space-frequency pilot design for multi-antenna wideband opportunistic communications 

    Borràs Pino, Jordi; Vázquez Grau, Gregorio (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    The statistical side information of interference channels is exploited in this paper to derive a novel uncoordinated on-line pilot design strategy for opportunistic communications. Assuming a time division duplex (TDD), ...
