    • DDPG Performance in THz Communications over Cascaded RISs: A Machine Learning Solution to the Over-Determined System 

      Shehab, Muhammad; Badawy, Ahmed; Elsayed, Mohamed; Khattab, Tamer; Trinchero, Daniele ( Institute of Electrical and Electronics Engineers Inc. , 2023 , Article)
      THz technology is considered a key element in 6G wireless communication because it provides ultra-high bandwidths, considerable capacities, and significant gains. However, wireless systems operating at high frequencies are ...

    • Exploiting Spatial Correlations: Group Key Generation for Secure IoT Device Networks 

      Omar, Mohammed; Badawy, Ahmed; Abulsaud, Khalid; Yaacoub, Elias; Guizani, Mohsen ( Institute of Electrical and Electronics Engineers Inc. , 2023 , Conference Paper)
      With the exponential growth in IoT devices, especially in healthcare systems, where multiple devices are attributed to one person, the need for a secure and effective group secret key (GSK) generation is intrinsic. GSKs ...

    • 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 ...

    • Optimized Resource and Deep Learning Model Allocation in O-RAN Architecture 

      Makhlouf, Ahmed; Abdellatif, Alaa Awad; Badawy, Ahmed; Mohamed, Amr ( IEEE Computer Society , 2023 , Conference Paper)
      In the era of 5G and beyond, telecommunication networks tend to move Radio Access Network (RAN) from centralized architecture to a more distributed architecture for greater interoperability and flexibility. Open RAN (O-RAN) ...

    • 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 ...
