Secure Communication with a Wireless-Powered Friendly Jammer
Wanchun Liu, Xiangyun Zhou, Salman Durrani +1
In this paper, we propose to use a wireless-powered friendly jammer to enable secure communication between a source node and destination node, in the presence of an eavesdropper. W…
Wireless-Powered Cooperative Communications via a Hybrid Relay
He Chen, Xiangyun Zhou, Yonghui Li +2
In this paper, we consider a wireless-powered cooperative communication network, which consists of a hybrid access-point (AP), a hybrid relay, and an information source. In contras…
Joint Resource Optimization for Multicell Networks with Wireless Energy Harvesting Relays
Ali A. Nasir, Duy T. Ngo, Xiangyun Zhou +2
This paper first considers a multicell network deployment where the base station (BS) of each cell communicates with its cell-edge user with the assistance of an amplify-and-forwar…
Cutting Last Wires for Mobile Communications by Microwave Power Transfer
Kaibin Huang, Xiangyun Zhou
The advancements in microwave power transfer (MPT) over past decades have enabled wireless power transfer over long distances. The latest breakthroughs in wireless communication, n…
A Semiblind Two-Way Training Method for Discriminatory Channel Estimation in MIMO Systems
Junjie Yang, Shengli Xie, Xiangyun Zhou +2
Discriminatory channel estimation (DCE) is a recently developed strategy to enlarge the performance difference between a legitimate receiver (LR) and an unauthorized receiver (UR)…
Training-Based SWIPT: Optimal Power Splitting at the Receiver
Xiangyun Zhou
We consider a point-to-point system with simultaneous wireless information and power transfer (SWIPT) over a block fading channel. Each transmission block consists of a training ph…
Performance Analysis of Arbitrarily-Shaped Underlay Cognitive Networks: Effects of Secondary User Activity Protocols
Jing Guo, Salman Durrani, Xiangyun Zhou
This paper analyzes the performance of the primary and secondary users (SUs) in an arbitrarily-shaped underlay cognitive network. In order to meet the interference threshold requir…
When Does Relay Transmission Give a More Secure Connection in Wireless Ad Hoc Networks?
Chunxiao Cai, Yueming Cai, Xiangyun Zhou +2
Relay transmission can enhance coverage and throughput, while it can be vulnerable to eavesdropping attacks due to the additional transmission of the source message at the relay. T…
