    • A Deep Reinforcement Learning Framework for Data Compression in Uplink NOMA-SWIPT Systems 

      El Sayed M.; Badawy A.; El Shafie A.; Mohamed A.; Khattab T. ( Institute of Electrical and Electronics Engineers Inc. , 2021 , Article)
      <comment< Non-orthogonal multiple access (NOMA) shall play an important role in the current and foreseeable design of 5G and beyond networks. NOMA allows multiple users to share the same time-frequency ...

    • A simple cross correlation switched beam system (XSBS) for angle of arrival estimation 

      Badawy A.; Khattab T.; Trinchero D.; Elfouly T.M.; Mohamed A. ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)
      We propose a practical, simple and hardware friendly, yet novel and efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation-based system requires a switched beam antenna array with ...

    • Deep Reinforcement Learning Algorithm for Smart Data Compression under NOMA-Uplink Protocol 

      Elsayed M.; Badawy A.; El Shafie A.; Mohamed A.; Khattab T. ( Institute of Electrical and Electronics Engineers Inc. , 2020 , Conference Paper)
      One of the highly promising radio access strategies for enhancing performance in the next generation cellular communications is non-orthogonal multiple access (NOMA). NOMA offers a number of advantages including better ...

    • Homomorphisms And Subalgebras Of Ms-Algebras 

      El-Assar, S.; Badawy, A. ( Qatar University , 1995 , Article)
      According to the characterization of MS-algcbras from the subvaricty Kj by mean of the triple construction, we characterize the homomorphisms and the subalgebras of the MS-algcbras. Also, we solve the "Fill-in" problem for ...

    • Non-data-aided SNR estimation for QPSK modulation in AWGN channel 

      Salman T.; Badawy A.; Elfouly T.M.; Khattab T.; Mohamed A. ( IEEE Computer Society , 2014 , Conference Paper)
      Signal-to-noise ratio (SNR) estimation is an important parameter that is required in any receiver or communication systems. It can be computed either by a pilot signal data-aided approach in which the transmitted signal ...

    • Secret key generation based on AoA estimation for low SNR conditions 

      Badawy A.; Khattab T.; El-Fouly T.; Mohamed A.; Trinchero D.; ... more authors ( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)
      In the context of physical layer security, a physical layer characteristic is used as a common source of randomness to generate the secret key. Therefore an accurate estimation of this characteristic is the core for reliable ...
