• Correlated Multiple Antennas Spectrum Sensing under Calibration Uncertainty 

      Pourgharehkhan, Zahra; Taherpour, Abbas; Sala-Alvarez, Josep; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      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 ...
    • Distributed spectrum sensing of correlated observations in cognitive radio networks 

      Sedighi, Saeid; Pourgharehkhan, Zahra; Taherpour, Abbas; Khattab, Tamer (2013 , Conference Paper)
      In this paper, Collaborative Spectrum Sensing (CSS) as one of the most efficient sensing approaches in Cognitive Radio Networks (CRNs) is investigated when the Secondary Users (SUs) observations are assumed to be correlated. ...
