User Scheduling and Trajectory Optimization for Energy-Efficient IRS-UAV Networks with SWIPT
S. Zargari, A. Hakimi, C. Tellambura +1
This paper investigates user scheduling and trajectory optimization for a network supported by an intelligent reflecting surface (IRS) mounted on an unmanned aerial vehicle (UAV).…
IRS-Enabled Backscattering in a Downlink Non-Orthogonal Multiple Access System
Azar Hakimi, Shayan Zargari, Chintha Tellambura +1
Intelligent reflecting surface (IRS)-enabled backscatter communications can be enabled by an access point (AP) that splits its transmit signal into modulated and unmodulated parts.…
Doppler Shift and Channel Estimation for Intelligent Transparent Surface Assisted Communication Systems on High-Speed Railways
Yirun Wang, Gongpu Wang, Ruisi He +2
The critical distinction between the emerging intelligent transparent surface (ITS) and intelligent reflection surface (IRS) is that the incident signals can penetrate the ITS inst…
Multiuser MISO PS-SWIPT Systems: Active or Passive RIS?
Shayan Zargari, Azar Hakimi, Chintha Tellambura +1
Reconfigurable intelligent surface (RIS)-based communication networks promise to improve channel capacity and energy efficiency. However, the promised capacity gains could be negli…
Energy-Efficient Hybrid Offloading for Backscatter-Assisted Wirelessly Powered MEC with Reconfigurable Intelligent Surfaces

We investigate a wireless power transfer (WPT)-based backscatter-mobile edge computing (MEC) network with a {reconfigurable intelligent surface (RIS)}.In this network, wireless dev…
Task Offloading with Multi-Tier Computing Resources in Next Generation Wireless Networks
Kunlun Wang, Jiong Jin, Yang Yang +4
With the development of next-generation wireless networks, the Internet of Things (IoT) is evolving towards the intelligent IoT (iIoT), where intelligent applications usually have…
New Antenna Selection Schemes for Full-Duplex Cooperative MIMO-NOMA Systems
Zahra Mobini, Mohammadali Mohammadi, Theodoros A. Tsiftsis +2
In this paper, we address the antenna selection (AS) problem in full-duplex (FD) cooperative non-orthogonal multiple access (NOMA) systems, where a multi-antenna FD relay bridges t…
