Wireless-Powered Relays in Cooperative Communications: Time-Switching Relaying Protocols and Throughput Analysis
Ali Arshad Nasir, Xiangyun Zhou, Salman Durrani +1
We consider wireless-powered amplify-and-forward and decode-and-forward relaying in cooperative communications, where an energy constrained relay node first harvests energy through…
Enhancing Secrecy with Multi-Antenna Transmission in Wireless Ad Hoc Networks
Xi Zhang, Xiangyun Zhou, Matthew R. McKay
We study physical-layer security in wireless ad hoc networks and investigate two types of multi-antenna transmission schemes for providing secrecy enhancements. To establish secure…
Wireless Physical Layer Security with Imperfect Channel State Information: A Survey
Biao He, Xiangyun Zhou, Thushara D. Abhayapala
Physical layer security is an emerging technique to improve the wireless communication security, which is widely regarded as a complement to cryptographic technologies. To design p…
Rethinking the Secrecy Outage Formulation: A Secure Transmission Design Perspective
Xiangyun Zhou, Matthew R. McKay, Behrouz Maham +1
This letter studies information-theoretic security without knowing the eavesdropper's channel fading state. We present an alternative secrecy outage formulation to measure the prob…
Analytical Evaluation of Coverage-Oriented Femtocell Network Deployment
He Wang, Xiangyun Zhou, Mark C. Reed
This paper proposes a coverage-oriented femtocell network deployment scheme, in which the femtocell base stations (BSs) can decide whether to be active or inactive depending on the…
Coverage and Throughput Analysis with a Non-Uniform Small Cell Deployment
He Wang, Xiangyun Zhou, Mark C. Reed
Small cell network (SCN) offers, for the first time, a low-cost and scalable mechanism to meet the forecast data-traffic demand. In this paper, we propose a non-uniform SCN deploym…
Secure On-Off Transmission Design with Channel Estimation Errors
Biao He, Xiangyun Zhou
Physical layer security has recently been regarded as an emerging technique to complement and improve the communication security in future wireless networks. The current research a…
Outage Probability in Arbitrarily-Shaped Finite Wireless Networks
Jing Guo, Salman Durrani, Xiangyun Zhou
This paper analyzes the outage performance in finite wireless networks. Unlike most prior works, which either assumed a specific network shape or considered a special location of t…
Physical Layer Security in Cellular Networks: A Stochastic Geometry Approach
He Wang, Xiangyun Zhou, Mark C. Reed
This paper studies the information-theoretic secrecy performance in large-scale cellular networks based on a stochastic geometry framework. The locations of both base stations and…
Outage Probability of Wireless Ad Hoc Networks with Cooperative Relaying
M. Mohammadi, H. A. Suraweera, X. Zhou
In this paper, we analyze the performance of cooperative transmissions in wireless ad hoc networks with random node locations. According to a contention probability for message tra…
Two-Way Training for Discriminatory Channel Estimation in Wireless MIMO Systems
Chao-Wei Huang, Tsung-Hui Chang, Xiangyun Zhou +1
This work examines the use of two-way training to efficiently discriminate the channel estimation performances at a legitimate receiver (LR) and an unauthorized receiver (UR) in a…
On the Design of Artificial-Noise-Aided Secure Multi-Antenna Transmission in Slow Fading Channels
Xi Zhang, Xiangyun Zhou, Matthew R. McKay
In this paper, we investigate the design of artificial-noise-aided secure multi-antenna transmission in slow fading channels. The primary design concerns include the transmit power…
