• DFT-Based Multi-Directions Directional Modulation 

      Hafez, Mohammed; Khattab, Tamer; Arslan, Hüseyin ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)
      In this letter, a physically secure multi-directions directional modulation scheme is proposed. The scheme provides an adaptive beam-width assignment, where each user is granted a different beam width based on its channel ...
    • Secure Communications Using Directional Modulation 

      Hafez, Mohammed; Khattab, Tamer; El-Fouly, Tarek; Arslan, Hüseyin ( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)
      Limitations on the wireless communication resources (i.e., time and frequency) introduces the need for another domain that can help communication systems to match the increasing demand on high data transfer rates and quality ...
    • Secure Spatial Multiple Access Using Directional Modulation 

      Hafez, Mohammed; Yusuf, Marwan; Khattab, Tamer; Elfouly, Tarek; Arslan, Hüseyin ( Institute of Electrical and Electronics Engineers Inc. , 2018 , Conference Paper)
      In this paper, we introduce a secure multiple access scheme, which exploits the multipath structure of the channel to create a multi-user interference environment. The generated interference enables legitimate users to ...
