Direction-Shift Keying for High-Mobility mmWave Communications: Geometry-Based Resilience to Short Channel Coherence Times and Phase Noise
Mohaned Chraiti, Ozgur Ercetin, Ali Ghrayeb +1
Communication reliability in high-mobility millimeter-wave (mmWave) systems is fundamentally challenged by rapid channel variations, manifested in short channel coherence times, an…
Secure Pinching Antenna-aided ISAC
Elmehdi Illi, Marwa Qaraqe, Ali Ghrayeb
In this letter, a pinching antenna (PA)-aided scheme for establishing a secure integrated sensing and communication system (ISAC) is investigated. The underlying system comprises a…
Theoretical and Experimental Assessment of Large Beam Codebook at mmWave Devices: How Much is Enough?
Bora Bozkurt, Hasan Atalay Gunel, Mohaned Chraiti +3
Modern millimeter wave (mmWave) transceivers come with a large number of antennas, each of which can support thousands of phase shifter configurations. This capability enables beam…
On the Secrecy-Sensing Optimization of RIS-assisted Full-Duplex Integrated Sensing and Communication Network
Elmehdi Illi, Ahmad Bazzi, Marwa Qaraqe +1
Integrated sensing and communication (ISAC) has recently emerged as a viable technique for establishing sensing and communication using the same resources. Nonetheless, the operati…
