Channel Estimation for OTFS Systems With Overspread Doppler Shifts
Preety Priya, Yi Hong, Emanuele Viterbo
In this paper, we consider an orthogonal time frequency space (OTFS) system in time-varying channels with overspread Doppler shifts, typically found in non-terrestrial multi-satell…
Corporate Bond Yield Curve Modeling: A Rating-Based Regime-Switching Generalized CIR Approach
Maochun Xu, Yunqi Liang, Yi Hong
Persistent shifts in term-structure dynamics undermine the stability of single-regime models in long samples. We develop an arbitrage-free regime-switching generalized CIR (RS-GCIR…
Stochastic Channel Models for Satellite Mega-Constellations
Brendon McBain, Yi Hong, Emanuele Viterbo
A general satellite channel model is proposed for communications between a rapidly moving low Earth orbit (LEO) satellite in a mega-constellation and a stationary user on Earth. Th…
Aerial Intelligent Reflecting Surface Enabled Terahertz Covert Communications in Beyond-5G Internet of Things
Milad Tatar Mamaghani, Yi Hong
Unmanned aerial vehicles (UAVs) are envisioned to be extensively employed for assisting wireless communications in Internet of Things (IoT) applications. On the other hand, teraher…
Terahertz Meets Untrusted UAV-Relaying: Minimum Secrecy Energy Efficiency Maximization via Trajectory and Communication Co-design
Milad Tatar Mamaghani, Yi Hong
Unmanned aerial vehicles (UAVs) and Terahertz (THz) technology are envisioned to play paramount roles in next-generation wireless communications. In this paper, we present a novel…
Joint Trajectory and Power Allocation Design for Secure Artificial Noise aided UAV Communications
Milad Tatar Mamaghani, Yi Hong
This paper investigates an average secrecy rate (ASR) maximization problem for an unmanned aerial vehicle (UAV) enabled wireless communication system, wherein a UAV is employed to…
Improving PHY-Security of UAV-Enabled Transmission with Wireless Energy Harvesting: Robust Trajectory Design and Communications Resource Allocation
Milad Tatar Mamaghani, Yi Hong
In this paper, we consider an unmanned aerial vehicle (UAV) assisted communications system, including two cooperative UAVs, a wireless-powered ground destination node leveraging si…
On the Performance of Low-Altitude UAV-Enabled Secure AF Relaying with Cooperative Jamming and SWIPT
Milad Tatar Mamaghani, Yi Hong
This paper proposes a novel cooperative secure unmanned aerial vehicle (UAV) aided transmission protocol, where a source (Alice) sends confidential information to a destination (Bo…
