On the Performance of RIS-Assisted Dual-Hop UAV Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In this paper, to further improve the coverage and performance of unmanned aerial vehicle (UAV) communication systems, we propose a reconfigurable intelligent surface (RIS)-assisted UAV scheme where an RIS installed on a ...
Secrecy Performance Analysis of RIS-Aided Wireless Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In this work, we study the secrecy performance of a reconfigurable intelligent surfaces (RIS)-aided wireless communication system in the presence of an eavesdropping user. Specifically, we assume that the RIS is placed ...
A Novel RIS-Assisted Modulation Scheme
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Article)
In this work, in order to achieve higher spectrum efficiency, we propose a reconfigurable intelligent surface (RIS)-assisted multi-user communication uplink system. Different from previous work in which the RIS only optimizes ...
Coverage, Probability of SNR Gain, and DOR Analysis of RiS-Aided Communication Systems
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
Recent studies have shown that reconfigurable Intelligent surfaces (RiSs) can help In extending the wireless coverage. However, no work has quantitatively analyzed the coverage. In this letter, we present the coverage ...
Amount of Secrecy Loss: A Novel Metric for Physical Layer Security Analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In this letter, we present a novel and important performance metric for analyzing and evaluating the physical layer security of wireless communication systems in the presence of eavesdropping users. Specifically, we introduce ...
