Compressive Sensing Based Multi-User Detector for the Large-Scale SM-MIMO Uplink
Zhen Gao, Linglong Dai, Zhaocheng Wang +2
Conventional spatial modulation (SM) is typically considered for transmission in the downlink of small-scale MIMO systems, where a single one of a set of antenna elements (AEs) is…
Iterative distributed minimum total-MSE approach for secure communications in MIMO interference channels
Zhengmin Kong, Shaoshi Yang, Feilong Wu +3
In this paper, we consider the problem of joint transmit precoding (TPC) matrix and receive filter matrix design subject to both secrecy and per-transmitter power constraints in th…
Distributed Energy Spectral Efficiency Optimization for Partial/Full Interference Alignment in Multi-User Multi-Relay Multi-Cell MIMO Systems
Kent Tsz Kan Cheung, Shaoshi Yang, Lajos Hanzo
The energy spectral efficiency maximization (ESEM) problem of a multi-user, multi-relay, multi-cell system is considered, where all the network nodes are equipped with multi-antenn…
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…
Space-Time Hierarchical-Graph Based Cooperative Localization in Wireless Sensor Networks
Tiejun Lv, Hui Gao, Xiaopeng Li +2
It has been shown that cooperative localization is capable of improving both the positioning accuracy and coverage in scenarios where the global positioning system (GPS) has a poor…
User Association in 5G Networks: A Survey and an Outlook
Dantong Liu, Lifeng Wang, Yue Chen +4
The fifth generation (5G) mobile networks are envisioned to support the deluge of data traffic with reduced energy consumption and improved quality of service (QoS) provision. To t…
Fifty Years of MIMO Detection: The Road to Large-Scale MIMOs
Shaoshi Yang, Lajos Hanzo
The emerging massive/large-scale MIMO (LS-MIMO) systems relying on very large antenna arrays have become a hot topic of wireless communications. Compared to the LTE based 4G mobile…
Relay Selection for Wireless Communications Against Eavesdropping: A Security-Reliability Tradeoff Perspective
Yulong Zou, Jia Zhu, Xuelong Li +1
