Zhimin Chen, Peng Chen, Le Zheng +1
Reconfigurable intelligent surface (RIS) or intelligent reflecting surface (IRS) has been an attractive technology for future wireless communication and sensing systems. However, i…
Reconfigurable Intelligent Surface Aided Sparse DOA Estimation Method With Non-ULA
Peng Chen, Zihan Yang, Zhimin Chen +1
The direction of arrival (DOA) estimation problem is addressed in this letter. A reconfigurable intelligent surface (RIS) aided system for the DOA estimation is proposed. Unlike tr…
Efficient DOA Estimation Method for Reconfigurable Intelligent Surfaces Aided UAV Swarm
Peng Chen, Zhimin Chen, Beixiong Zheng +1
The conventional direction of arrival (DOA) estimation methods are performed with multiple receiving channels. In this paper, a changeling DOA estimation problem is addressed in a…
A New Store-then-Amplify-and-Forward Protocol for UAV Mobile Relaying
Xiaochen Lin, Weidong Mei, Rui Zhang
In this letter, we consider the use of an unmanned aerial vehicle (UAV) as a mobile relay to assist the communication between two ground users without a direct link. We propose a n…
