• Blind SNR Estimation of Gaussian-Distributed Signals in Nakagami Fading Channels 

      Hafez, Mohammed; Khattab, Tamer; Shalaby, Hossam M. H. ( IEEE , 2015 , Article)
      A blind (non-data-aided) SNR estimator using the statistical moments of the received signal is proposed. The proposed envelope-based non-data-aided estimator works for any time-domain Gaussian-distributed signal (e.g. OFDM ...
    • To Relay or Not To Relay in Cognitive Radio Sensor Networks 

      Foukalas, F.; Khattab, T. ( IEEE , 2014 , Article)
      A recent investigation on MAC layer in cognitive radio networks proposed the primary packet relaying by the secondary node maintaining an extra queue used for this particular addable functionality. Nevertheless, relaying ...
