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…
Secure Degrees of Freedom of the Gaussian MIMO Wiretap and MIMO Broadcast Channels with Unknown Eavesdroppers
Mohamed Amir, Tamer Khattab, Tarek Elfouly +1
We investigate the secure degrees of freedom (SDoF) of the wiretap and the K user Gaussian broadcast channels with multiple antennas at the transmitter, the legitimate receivers an…
