Secure Near-Field ISAC with Pinching-Antenna Systems: Exploiting Constructive-Destructive Interference
Dimitrios Bozanis, Vasilis K. Papanikolaou, Sotiris A. Tegos +3
This paper investigates secure near-field integrated sensing and communication (ISAC) with pinching-antenna systems (PASS), where a base station serves legitimate users while local…
Pinching Antenna-Assisted Full-Duplex Communication Systems
Xuan Li, Xianfu Lei, Mingjiang Wu +3
Full-duplex (FD) communication theoretically doubles spectral efficiency. Despite this potential, its practical performance is primarily constrained by severe self-interference (SI…
Secure ISAC with Sensing Privacy under Eavesdropper Uncertainty
Pigi P. Papanikolaou, Dimitrios Bozanis, Sotiris A. Tegos +2
This paper investigates the joint protection of confidential data and legitimate-user directional information in integrated sensing and communication (ISAC) networks. We consider a…
Breaking Network Densification Limits with Distributed Cooperative Massive Access (DCMA)
Christoforos I. Dallas, Apostolos A. Tegos, Sotiris A. Tegos +3
In this work, we investigate the performance of the distributed cooperative massive access (DCMA) framework in large-scale network setups by incorporating stochastic geometry model…
Jacobi Elliptic Chirps for Sub-Nyquist Multi-Target Ranging
Dimitrios Bozanis, Thrassos K. Oikonomou, Sotiris A. Tegos +2
Sub-Nyquist sampling is an attractive way to reduce the hardware cost of wideband pulse-compression radar, but it introduces coherent alias-induced replicas in the matched-filter r…
Elliptic Range-Doppler Mapping for OFDM-ISAC under IQ Imbalance
Thrassos K. Oikonomou, Dimitrios Bozanis, Sotiris A. Tegos +2
Receiver in-phase/quadrature imbalance (IQI) couples each OFDM subcarrier with its mirror counterpart, creating ghost targets and degrading range-Doppler recovery in orthogonal fre…
Quantized Zero-Energy RIS: Residual Phase Modeling and Outage Analysis
Dimitrios Tyrovolas, Sotiris A. Tegos, Kunrui Cao +6
Zero-energy reconfigurable intelligent surfaces (zeRISs) have recently emerged as a promising solution for enabling energy-efficient and scalable programmable wireless environments…
Constellation Design for Robust Interference Mitigation
Athanasios T. Papadopoulos, Thrassos K. Oikonomou, Dimitrios Tyrovolas +4
This paper investigates symbol detection for single-carrier communication systems operating in the presence of additive interference with Nakagami-m statistics. Such interference d…
Improving Reliability of Hybrid Bit-Semantic Communications for Cellular Networks
Nikos G. Evgenidis, Sotiris A. Tegos, Panagiotis D. Diamantoulakis +2
Semantic communications (SemComs) have been considered as a promising solution to reduce the amount of transmitted information, thus paving the way for more energy-and spectrum-eff…
When Simultaneous Localization and Mapping Meets Wireless Communications: A Survey
Konstantinos Gounis, Sotiris A. Tegos, Dimitrios Tyrovolas +2
This paper surveys the state-of-the-art in the nexus of SLAM and Wireless Communications, attributing the bidirectional impact of each with a focus on visual SLAM (V-SLAM) integrat…
