Impact of Pointing Errors and Correlated Wall Blockages on Practical Grid-based Indoor Terahertz Communication Systems
Zhifeng Tang, Nan Yang, Salman Durrani +3
Terahertz (THz) communications has emerged as a promising technology for future wireless systems due to its potential to support extremely high data rates. However, severe path los…
Symbol-Aware Precoder Design for Physical-Layer Anonymous Communications
Yu Li, Milad Tatar Mamaghani, Xiangyun Zhou +1
Physical-layer characteristics, such as channel state information (CSI) and transmitter noise induced by hardware impairments, are often uniquely associated with a transmitter. Thi…
Impact of Pointing Error on Coverage Performance of 3D Indoor Terahertz Communication Systems
Zhifeng Tang, Nan Yang, Xiangyun Zhou +3
In this paper, we develop a tractable analytical framework for a three-dimensional (3D) indoor terahertz (THz) communication system to theoretically assess the impact of the pointi…
Near-Field Secure Beamfocusing With Receiver-Centered Protected Zone
Cen Liu, Xiangyun Zhou, Nan Yang +2
This work studies near-field secure communications through transmit beamfocusing. We examine the benefit of having a protected eavesdropper-free zone around the legitimate receiver…
Securing Integrated Sensing and Communication Against a Mobile Adversary: A Stackelberg Game with Deep Reinforcement Learning
Milad Tatar Mamaghani, Xiangyun Zhou, Nan Yang +1
In this paper, we study a secure integrated sensing and communication (ISAC) system employing a full-duplex base station with sensing capabilities against a mobile proactive advers…
Low Complexity Artificial Noise Aided Beam Focusing Design in Near-Field Terahertz Communications
Zhifeng Tang, Nan Yang, Xiangyun Zhou +3
In this paper, we develop a novel low-complexity artificial noise (AN) aided beam focusing scheme in a near-field terahertz wiretap communication system. In this system, the base s…
