    • Detection of temporally correlated primary user signal with multiple antennas 

      Hashemi, Hadi; Fard, Sina Mohammadi; Taherpour, Abbas; Sedighi, Saeid; Khattab, Tamer ( Springer Verlag , 2015 , Conference Paper)
      In this paper, we address the problem of multiple antenna spectrum sensing in cognitive radios (CRs) when the samples of the primary user (PU) signal as well as samples of noise are assumed to be temporally correlated. We ...

    • 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. ...

    • Eigenvalue-Based Multiple Antenna Spectrum Sensing: Higher Order Moments 

      Sedighi, Saeid; Taherpour, Abbas; Gazor, Saeed; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)
      The problem of multiple antenna spectrum sensing in cognitive radio (CR) networks is studied in this paper. We propose two new invariant constant false-alarm rate eigenvalue-based (EVB) detectors, using the higher order ...

    • Finite-sample size multiple antennas spectrum sensing 

      Sedighi, Saeid; Taherpour, Abbas; Khattab, Tamer (2012 , Conference Paper)
      In this paper, we consider the problem of multiple antenna spectrum sensing in Cognitive Radios (CR) by exploiting the prior information about unknown parameters. Specifically, we consider a blind spectrum sensing problem ...

    • Multiple antenna cyclostationary-based detection of primary users with multiple cyclic frequency in Cognitive Radios 

      Sedighi, Saeid; Taherpour, Abbas; Khattab, Tamer; Hasna, Mazen O. ( IEEE , 2014 , Conference Paper)
      In this paper, we study the problem of multiple antenna spectrum sensing by using cyclostationary features of Primary Users (PUs) signals in Cognitive Radios (CRs). We consider the general case of multiple antenna sensing ...

    • On the Performance of Hadamard Ratio Detector-Based Spectrum Sensing for Cognitive Radios 

      Sedighi, Saeid; Taherpour, Abbas; Sala-Alvarez, Josep; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)
      We consider the problem of multiantenna spectrum sensing (SS) in cognitive radios (CRs) when the receivers are assumed to be uncalibrated across the antennas. The performance of the Hadamard Ratio Detector (HRD) is analyzed ...

    • SFET-based multiple antenna spectrum sensing using the second order moments of eigenvalues 

      Sedighi, Saeid; Taherpour, Abbas; Gazor, Saeed; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      In this paper, we propose a new detector for multiantenna spectrum sensing in cognitive radios (CR) by exploiting the Separating Function Estimation Test (SFET) framework. Specifically, we consider a blind scenario for ...
