Hardware Impairments Aware Transceiver for Full-Duplex Massive MIMO Relaying
Xiaochen Xia, Dongmei Zhang, Kui Xu +2
This paper studies the massive MIMO full-duplex relaying (MM-FDR), where multiple source-destination pairs communicate simultaneously with the help of a common full-duplex relay eq…
Joint Relay and Jammer Selection Improves the Physical Layer Security in the Face of CSI Feedback Delays
Lei Wang, Yueming Cai, Yulong Zou +2
We enhance the physical-layer security (PLS) of amplify-and-forward relaying networks with the aid of joint relay and jammer selection (JRJS), despite the deliterious effect of cha…
A Game Theoretic Perspective on Self-organizing Optimization for Cognitive Small Cells
Yuhua Xu, Jinlong Wang, Qihui Wu +3
In this article, we investigate self-organizing optimization for cognitive small cells (CSCs), which have the ability to sense the environment, learn from historical information, m…
Dynamic Spectrum Access in Time-varying Environment: Distributed Learning Beyond Expectation Optimization
Yuhua Xu, Jinlong Wang, Qihui Wu +3
This article investigates the problem of dynamic spectrum access for canonical wireless networks, in which the channel states are time-varying. In the most existing work, the commo…
Load-aware Dynamic Spectrum Access for Small Cell Networks: A Graphical Game Approach
Yuhua Xu, Chenggui Wang, Junhong Chen +4
In this letter, we investigate the problem of dynamic spectrum access for small cell networks, using a graphical game approach. Compared with existing studies, we take the features…
Database-assisted Spectrum Access in Dynamic Networks: A Distributed Learning Solution
Yuhua Xu, Yitao Xu, Alagan Anpalagan
This paper investigates the problem of database-assisted spectrum access in dynamic TV white spectrum networks, in which the active user set is varying. Since there is no central c…
