Fundamental Rate Limits of Physical Layer Spoofing
Jie Xu, Lingjie Duan, Rui Zhang
This letter studies an emerging wireless communication intervention problem at the physical layer, where a legitimate spoofer aims to spoof a malicious link from Alice to Bob, by r…
Surveillance and Intervention of Infrastructure-Free Mobile Communications: A New Wireless Security Paradigm
Jie Xu, Lingjie Duan, Rui Zhang
Conventional wireless security assumes wireless communications are rightful and aims to protect them against malicious eavesdropping and jamming attacks. However, emerging infrastr…
Dynamic routing for social information sharing
Yunpeng Li, Costas Courcoubetis, Lingjie Duan
Today mobile users are intensively interconnected thanks to the emerging mobile social networks, where they share location-based information with each other when traveling on diffe…
Transmit Optimization for Symbol-Level Spoofing
Jie Xu, Lingjie Duan, Rui Zhang
With recent developments of wireless communication technologies, malicious users can use them to commit crimes or launch terror attacks, thus imposing new threats on the public sec…
Harnessing Self-Interference in Full-Duplex Relaying: An Analog Filter-and-Forward Approach
Jie Xu, Lingjie Duan, Rui Zhang
This paper studies a full-duplex filter-and-forward (FD-FF) relay system in frequency-selective channels. Conventionally, the loop-back signal at the FD relay is treated as harmful…
Two-sided Matching Based Cooperative Spectrum Sharing
Lin Gao, Lingjie Duan, Jianwei Huang
Dynamic spectrum access (DSA) can effectively improve the spectrum efficiency and alleviate the spectrum scarcity, by allowing unlicensed secondary users (SUs) to access the licens…
Optimal Pricing and Admission Control for Heterogeneous Secondary Users
Changkun Jiang, Lingjie Duan, Jianwei Huang
This paper studies how to maximize a spectrum database operator's expected revenue in sharing spectrum to secondary users, through joint pricing and admission control of spectrum r…
Green 5G Heterogeneous Networks through Dynamic Small-Cell Operation
Shijie Cai, Yueling Che, Lingjie Duan +3
Traditional macro-cell networks are experiencing an upsurge of data traffic, and small-cells are deployed to help offload the traffic from macro-cells. Given the massive deployment…
