Designing Wireless Powered Networks assisted by Intelligent Reflecting Surfaces with Mechanical Tilt
Zoran Hadzi-Velkov, Slavche Pejoski, Nikola Zlatanov +1
In this paper, we propose a fairness-aware rate maximization scheme for a wireless powered communications network (WPCN) assisted by an intelligent reflecting surface (IRS). The pr…
Optimal Power and Time Allocation for WPCNs with Piece-wise Linear EH Model
Slavche Pejoski, Zoran Hadzi-Velkov, Robert Schober
We propose a novel transmission protocol for harvest-then-transmit wireless powered communication networks, which takes into account the non-linearity of the energy harvesting (EH)…
Wireless Powered Communication Networks with Non-Ideal Circuit Power Consumption
Slavche Pejoski, Zoran Hadzi-Velkov, Trung Q. Duong +1
Assuming non-ideal circuit power consumption at the energy harvesting (EH) nodes, we propose two practical protocols that optimize the performance of the harvest-then-transmit wire…
Performance Comparison Between A Simple Full-Duplex Multi-Antenna Relay And A Passive Reflecting Intelligent Surface
Armin Bazrafkan, Marija Poposka, Zoran Hadzi-Velkov +2
In this paper, we propose to investigate a single RF chain multi-antenna full-duplex (FD) relay built with -bit analog phase shifters and passive self-interference cancellation.…
Proportional Fairness in ALOHA Networks with RF Energy Harvesting
Zoran Hadzi-Velkov, Slavche Pejoski, Nikola Zlatanov +1
In this paper, we study wireless powered communication networks that employ the slotted ALOHA protocol, which is the preferred protocol for simple and uncoordinated networks. In th…
On the Secrecy Capacity of a Full-Duplex Wirelessly Powered Communication System
Ivana Nikoloska, Nikola Zlatanov, Zoran Hadzi-Velkov +1
In this paper, we investigate the secrecy capacity of a point-to-point, full-duplex (FD) wirelesly powered communication system in the presence of a passive eavesdropper (EVE). The…
