Jacobi Elliptic Chirps for Sub-Nyquist Multi-Target Ranging
Dimitrios Bozanis, Thrassos K. Oikonomou, Sotiris A. Tegos +2
The paper introduces a sine‑over‑cosine Jacobi elliptic chirp (SC‑EFM) for sub‑Nyquist pulse‑compression radar, showing it can suppress ghost‑target artifacts while preserving targ…
Elliptic Range-Doppler Mapping for OFDM-ISAC under IQ Imbalance
Thrassos K. Oikonomou, Dimitrios Bozanis, Sotiris A. Tegos +2
The paper proposes a new detection algorithm that directly exploits the structure of IQ‑imbalance‑distorted OFDM signals for integrated sensing and communication, using an elliptic…
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…
Physical Layer Security with Artificial Noise in MIMO Pinching-Antenna Systems
Pigi P. Papanikolaou, Dimitrios Bozanis, Sotiris A. Tegos +3
As next-generation wireless networks emerge, security is becoming a critical performance metric. However, conventional multiple-input-multiple-output (MIMO) systems often suffer fr…
Constellation Design and Detection under Generalized Hardware Impairments
Thrassos K. Oikonomou, Dimitrios Tyrovolas, Sotiris A. Tegos +3
This paper presents a maximum-likelihood detection framework that jointly mitigates hardware (HW) impairments in both amplitude and phase. By modeling transceiver distortions as re…
