Beamforming for MISO Interference Channels with QoS and RF Energy Transfer
Stelios Timotheou, Ioannis Krikidis, Gan Zheng +1
We consider a multiuser multiple-input single-output interference channel where the receivers are characterized by both quality-of-service (QoS) and radio-frequency (RF) energy har…
Low-complexity End-to-End Performance Optimization in MIMO Full-Duplex Relay Systems
Himal A. Suraweera, Ioannis Krikidis, Gan Zheng +2
In this paper, we deal with the deployment of full-duplex relaying in amplify-and-forward (AF) cooperative networks with multiple-antenna terminals. In contrast to previous studies…
Simultaneous Information and Energy Transfer in Large-Scale Networks with/without Relaying
Ioannis Krikidis
Energy harvesting (EH) from ambient radio-frequency (RF) electromagnetic waves is an efficient solution for fully autonomous and sustainable communication networks. Most of the rel…
Improving Physical Layer Secrecy Using Full-Duplex Jamming Receivers
Gan Zheng, Ioannis Krikidis, Jiangyuan Li +2
This paper studies secrecy rate optimization in a wireless network with a single-antenna source, a multi-antenna destination and a multi-antenna eavesdropper. This is an unfavorabl…
Constructive Interference in Linear Precoding Systems: Power Allocation and User Selection
Dimitrios Christopoulos, Symeon Chatzinotas, Ioannis Krikidis +1
The exploitation of interference in a constructive manner has recently been proposed for the downlink of multiuser, multi-antenna transmitters. This novel linear precoding techniqu…
Full-Duplex Cooperative Cognitive Radio with Transmit Imperfections
Gan Zheng, Ioannis Krikidis, Bjorn Ottersten
This paper studies the cooperation between a primary system and a cognitive system in a cellular network where the cognitive base station (CBS) relays the primary signal using ampl…
