Enhancing Satellite Link Security Against Drone Eavesdropping Through Cooperative Communication
International Journal of Satellite Communications and Networking, Volume 43, Issue 1, Page 10-22, January/February 2025.ABSTRACT Integrated satellite terrestrial networks (ISTNs) are emerging as a promising next‐generation communication technology, for example, B5G and 6G, with low‐earth orbit (LEO) satellites playing a growing role. However, the complex and unique characteristics of ISTNs make them more susceptible to cyberattacks.

Artificial Noise Aided Precoding With Imperfect CSI in Full-Duplex Relaying Secure Communications
IEEE Access, 2018 In Rayleigh fading channels, to enhance the secrecy performance of wireless communication systems and efficiently disturb the interception of eavesdroppers, the multiple-antenna source node utilizes the artificial noise aided precoding (ANP) strategy ...

Fat‐tailed DSGE models: A survey and new results
Journal of Economic Surveys, Volume 39, Issue 1, Page 146-171, February 2025.Abstract We review recent advances in dynamic stochastic general equilibrium theory concerned with the emergence of fat‐tailed time‐series distributions. Focusing on mechanisms that are firmly grounded in structural equilibrium models, we provide a common reference framework to organize existing contributions according to whether they entail extreme ...

Secrecy Enhancement of Cooperative NOMA Networks With Two-Way Untrusted Relaying
IEEE Access, 2020 The two-way relaying (TWR) technique has been confirmed to achieve higher spectral efficiency and average sum rate compared with the one-way relaying (OWR) technique in ultra-dense next generation networks with limited spectal resources.

Secrecy Through Synchronization Errors
, 2015 In this paper, we propose a transmission scheme that achieves information theoretic security, without making assumptions on the eavesdropper's channel. This is achieved by a transmitter that deliberately introduces synchronization errors (insertions and ...
