Latency Decoupling in Low-Feedback Multi-User Networks via Overhearing-Driven NOMA
Mohsen Abedi, Ahmed Badawy, Amr Mohamed
Conventional wireless protocols such as Hybrid Automatic Repeat Request (HARQ) rely on frequent and timely feedback, which becomes impractical in low-feedback regimes including non…
Terahertz Multiple Access: A Deep Reinforcement Learning Controlled Multihop IRS Topology
Muhammad Shehab, Abdullateef Almohamad, Mohamed Elsayed +5
We investigate THz communication uplink multiple access using cascaded intelligent reflecting surfaces (IRSs) assuming correlated channels. Two independent objectives to be achieve…
Securing OFDM-Based NOMA SWIPT Systems
Ahmed Badawy, Ahmed El Shafie
In this paper, we present a physical-layer security scheme that exploits artificial noise (AN) to secure the downlink legitimate communications and transfer energy to nodes operati…
On the Performance of Quickest Detection Spectrum Sensing: The Case of Cumulative Sum
Ahmed Badawy, Ahmed El Shafie, Tamer Khattab
Quickest change detection (QCD) is a fundamental problem in many applications. Given a sequence of measurements that exhibits two different distributions around a certain flipping…
Estimating the Number of Sources: An Efficient Maximization Approach
Tara Salman, Ahmed Badawy, Tarek M. Elfouly +2
Estimating the number of sources received by an antenna array have been well known and investigated since the starting of array signal processing. Accurate estimation of such param…
Secret Key Generation Based on AoA Estimation for Low SNR Conditions
Ahmed Badawy, Tamer Khattab, Tarek Elfouly +3
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…
