Reconfigurable non-reciprocal wave growth in spatiotemporal modulated 1-D crystal
Mohamed F. Hagag, Thomas R. Jones, Karim Seddik +1
Nonreciprocity in space-time modulated photonic crystals has been investigated in the context of nonreciprocal propagation and polarization. Here, we investigate a reconfigurable n…
Signal Amplification in a Time-Modulated Transmission Line and the Loss Effect
Mohamed Hagag, Thomas Robert Jones, Karim Seddik +1
We investigate and simulate signal amplification in a transmission line (TL) with time-modulated characteristic impedance Zo. Periodically varying is achieved by loading TL w…
Robust Joint Active-Passive Beamforming Design for IRS-Assisted ISAC Systems
Mahmoud AlaaEldin, Emad Alsusa, Karim G. Seddik +2
The idea of Integrated Sensing and Communication (ISAC) offers a promising solution to the problem of spectrum congestion in future wireless networks. This paper studies the integr…
Asymmetric Degrees of Freedom of the Full-Duplex MIMO 3-Way Channel with Unicast and Broadcast Messages
Adel M. Elmahdy, Amr El-Keyi, Yahya Mohasseb +4
In this paper, we characterize the asymmetric total degrees of freedom (DoF) of a multiple-input multiple-output (MIMO) 3-way channel. Each node has a separate-antenna full-duplex…
A Soft Sensing-Based Cognitive Access Scheme Exploiting Primary Feedback
Ahmed M. Arafa, Karim G. Seddik, Ahmed K. Sultan +2
In this paper, we examine a cognitive spectrum access scheme in which secondary users exploit the primary feedback information. We consider an overlay secondary network employing a…
A Diversity-Multiplexing-Delay Tradeoff of ARQ Protocols in The Z-interference Channel
Mohamed S. Nafea, D. Hamza, Karim G. Seddik +2
In this work, we analyze the fundamental performance tradeoff of the single-antenna Automatic Retransmission reQuest (ARQ) Z-interference channel (ZIC). Specifically, we characteri…
