    • A hybrid spectrum sensing technique with multiple antenna based on GLRT 

      Badawy, Ahmed; Khattab, Tamer (2013 , Conference Paper)
      Spectrum sensing is the core for any cognitive radio network. Quick detection of the primary user signal allows for higher spectrum efficiency. In this paper, we introduce and implement a new hybrid spectrum sensing technique ...

    • A novel peak search & save cyclostationary feature detection algorithm 

      Badawy, Ahmed; Khattab, Tamer ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      Spectrum sensing is a key task in any cognitive radio network. On the other hand, a literature survey in this topic shows a lack of implementation and testbeds for spectrum sensing techniques. In this paper, we plot the ...

    • Efficient FPGA-based implementation of a novel dual mode spectrum sensing technique 

      Badawy, Ahmed; Khattab, Tamer (2013 , Conference Paper)
      Cognitive radio networks require an efficient and reliable method of sensing the spectrum. In this paper, we introduce and implement a new dual mode spectrum sensing technique that is based on combining Quickest Detection ...

    • Exploiting spectrum sensing data for key management 

      Badawy, Ahmed; Elfouly, Tarek; Chiasserini, Carla-Fabiana; Khattab, Tamer; Trinchero, Daniele ( Elsevier B.V. , 2017 , Article)
      In cognitive radio networks, secondary users (SUs) communicate on unused spectrum slots in the frequency bands assigned to primary users (PUs). Like any other wireless communication system, cognitive radio networks are ...

    • A Hardware Based Ricean Fading Radio Channel Simulator 

      Badawy, Ahmed; Wolff, Richard ( IEEE Xplore , 2017 , Conference Paper)
      The rise of the need of fading radio channel simulators is due to time and cost of field tests of wireless communications systems. Growth in the demand for fixed wireless access increases the need for wide area system ...

    • Order Statistics-Based Design of UWB Receivers 

      Badawy, Ahmed; Elfouly, Tarek; Khattab, Tamer; Chiasserini, Carla Fabiana; Trinchero, Daniele ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)
      We propose a non-coherent ultra-wideband (UWB) receiver that leverages a single-sample-per-pulse threshold approach to detect the transmitted symbol and is capable of mitigating the impact of impulse noise. Unlike classical ...
