DFT-based multi-directions directional modulation
Hafez, Mohammed; Khattab, Tamer; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers, 2019)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 spatial multiple access using directional modulation
Hafez, Mohammed; Yusuf, Marwan; Khattab, Tamer; Elfouly, Tarek; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)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 ... -
Smart and secure wireless communications via reflecting intelligent surfaces: A short survey
Almohamad, Abdullateef; M. Tahir, Anas; Al-Kababji, Ayman; Madni, Haji Muhammad Furqan Ahmed; Khattab, Tamer; Hasna, Mazen Omar; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)With the emergence of the Internet of Things (IoT) technology, wireless connectivity should be more ubiquitous than ever. In fact, the availability of wireless connection everywhere comes with security threats that, ... -
Thresholds optimization for one-bit feedback multi-user scheduling
Hafez, Mohammed; El Shafie, Ahmed; Shaqfeh, Mohammed; Khattab, Tamer; Alnuweiri, Hussein; Arslan, Hüseyin (Institute of Electrical and Electronics Engineers Inc., 2018)We propose a new one-bit feedback scheme with scheduling decision based on the maximum expected weighted rate. We show the concavity of the 2-user case and provide the optimal solution which achieves the maximum weighted ...
