Exploiting Known Interference as Green Signal Power for Downlink Beamforming Optimization
C. Masouros, G. Zheng
We propose a data-aided transmit beamforming scheme for the multi-user multiple-input-single-output (MISO) downlink channel. While conventional beamforming schemes aim at the minim…
Secrecy Analysis on Network Coding in Bidirectional Multibeam Satellite Communications
Ashkan Kalantari, Gan Zheng, Zhen Gao +2
Network coding is an efficient means to improve the spectrum efficiency of satellite communications. However, its resilience to eavesdropping attacks is not well understood. This p…
Full-Duplex MIMO Relaying Powered by Wireless Energy Transfer
Mohammadali Mohammadi, Himal A. Suraweera, Gan Zheng +2
We consider a full-duplex decode-and-forward system, where the wirelessly powered relay employs the time-switching protocol to receive power from the source and then transmit infor…
Optimum Wirelessly Powered Relaying
Caijun Zhong, Gan Zheng, Zhaoyang Zhang +1
This paper maximizes the achievable throughput of a relay-assisted wirelessly powered communications system, where an energy constrained source, helped by an energy constrained rel…
Physical Layer Security for Massive MIMO: An Overview on Passive Eavesdropping and Active Attacks
Dzevdan Kapetanovic, Gan Zheng, Fredrik Rusek
This article discusses opportunities and challenges of physical layer security integration in massive multiple-input multiple-output (MaMIMO) systems. Specifically, we first show t…
