    • A review of RFI mitigation techniques in microwave radiometry 

      Querol, Jorge; Pérez Portero, Adrián; Camps Carmona, Adriano José (Multidisciplinary Digital Publishing Institute (MDPI), 2019-12-17)
      Article
      Open Access
      Radio frequency interference (RFI) is a well-known problem in microwave radiometry (MWR). Any undesired signal overlapping the MWR protected frequency bands introduces a bias in the measurements, which can corrupt the ...
    • Architectures and synchronization techniques for coherent distributed remote sensing systems 

      Merlano-Duncan, Juan Carlos; Querol, Jorge; Camps Carmona, Adriano José; Chatzinotas, Simeon; Ottersten, Bjorn (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture

      Phase, frequency and time synchronization is a crucial requirement for many applications as such as multi-static remote sensing and distributed beamforming for communications. The literature on the field is very wide, and ...
    • Effects of differential oscillator phase noise in precoding performance 

      Martínez Marrero, Liz; Merlano-Duncan, Juan Carlos; Querol, Jorge; Chatzinotas, Symeon; Camps Carmona, Adriano José; Ottersten, Björn (2019)
      Conference report
      Restricted access - publisher's policy
      Satellite Precoding is a promising technique to meet the target data rates of the future high throughput satellite systems and the costs per bit as required by 5G applications and networks, but it requires strict synchronization ...
    • Implementation of a testbed for GNSS-R payload performance evaluation 

      Pérez Portero, Adrián; Muñoz Martin, Joan Francesc; Querol, Jorge; Hyuk, Park; Camps Carmona, Adriano José (Institute of Electrical and Electronics Engineers (IEEE), 2020-05-28)
      Article
      Open Access
      The functional performance of space-borne instruments must be validated on ground before and after satellite integration. The effects of radio-frequency interference are also becoming more important, even in protected bands ...
    • On the new architecture and capabilities of the front-End GNSS interference excisor (Fenix) 

      Pérez Portero, Adrián; Camps Carmona, Adriano José; Querol, Jorge (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference lecture
      Restricted access - publisher's policy
      The number of applications based on Global Navigation Satellite Systems (GNSS) has been increasing in the last years. With its proliferation, Radio-Frequency Interference (RFI) has become one of the most concerning topics ...
