AN-aided Secure Transmission in Multi-user MIMO SWIPT Systems
Zhengyu Zhu, Ning Wang, Zheng Chu +2
In this paper, an energy harvesting scheme for a multi-user multiple-input-multiple-output (MIMO) secrecy channel with artificial noise (AN) transmission is investigated. Joint opt…
Energy Harvesting Fairness in AN-aided Secure MU-MIMO SWIPT Systems with Cooperative Jammer
Zhengyu Zhu, Zheng Chu, Ning Wang +2
In this paper, we study a multi-user multiple-input-multiple-output secrecy simultaneous wireless information and power transfer (SWIPT) channel which consists of one transmitter,…
Energy Efficiency Maximization for CoMP Joint Transmission with Non-Ideal Power Amplifiers
Yuhao Zhang, Qimei Cui, Ning Wang
Coordinated multipoint (CoMP) joint transmission (JT) can save a great deal of energy especially for cell-edge users due to strengthened received signal, but at the cost of deployi…
Energy-Efficient User Access Control and Resource Allocation in HCNs with Non-Ideal Circuitry
Yuhao Zhang, Qimei Cui, Ning Wang
In this paper, we study the energy-efficient user access control (UAC) based on resource allocation (RA) in heterogeneous cellular networks (HCNs) with the required downlink data r…
Optimal Pilot Symbols Ratio in terms of Spectrum and Energy Efficiency in Uplink CoMP Networks
Yuhao Zhang, Qimei Cui, Ning Wang
In wireless networks, Spectrum Efficiency (SE) and Energy Efficiency (EE) can be affected by the channel estimation that needs to be well designed in practice. In this paper, consi…
