    One of the main applications of SAR interferometry is the monitoring of hazard risks related with urban subsidence and landslide instabilities. The different sensors available offer different carrier frequencies, image ...
  • A High-Efficiency RF Harvester with Maximum Power Point Tracking 

    Gasulla Forner, Manuel; Robert Sanxis, Francesc Josep; Jordana Barnils, José; Ripoll Vercellone, Edgar; Berenguer Sau, Jordi; Reverter Cubarsí, Ferran (Multidisciplinary Digital Publishing Institute (MDPI), 2018)
    Conference report
    Open Access
    This paper presents the implementation of a high-efficiency radiofrequency (RF) harvester, which consists of a rectenna and a maximum power point tracker (MPPT). The rectenna was characterized from -30 dBm to -10 dBm at ...
  • Dynamic service reallocation in NFV-based transport WDM optical networks 

    Pagès Cruz, Albert; Agraz Bujan, Fernando; Montero, Rafael; Spadaro, Salvatore (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Conference report
    Restricted access - publisher's policy
    Future network services are expected to deliver additional functionalities besides connectivity. The Network Function Virtualization (NFV) paradigm provides the foundation for such concept. We propose a reallocation-based ...
  • Experimental assessment of 5-10Gbps 5G multicarrier waveforms with intensity-modulation direct-detection for PONs
