Intelligent Reflecting Surface Assisted Anti-Jamming Communications Based on Reinforcement Learning
Helin Yang, Zehui Xiong, Jun Zhao +4
Malicious jamming launched by smart jammer, which attacks legitimate transmissions has been regarded as one of the critical security challenges in wireless communications. Thus, th…
Intelligent Reflecting Surface Aided MISO Uplink Communication Network: Feasibility and Power Minimization for Perfect and Imperfect CSI
Yang Liu, Jun Zhao, Ming Li +1
In this paper, we consider the weighted sum-power minimization under quality-of-service (QoS) constraints in the multi-user multi-input-single-output (MISO) uplink wireless network…
Covert Communication in Intelligent Reflecting Surface-Assisted NOMA Systems: Design, Analysis, and Optimization
Lu Lv, Qingqing Wu, Zan Li +3
In this paper, we investigate covert communication in an intelligent reflecting surface (IRS)-assisted non-orthogonal multiple access (NOMA) system, where a legitimate transmitter…
Joint Beamforming Design and Power Splitting Optimization in IRS-Assisted SWIPT NOMA Networks
Zhendong Li, Wen Chen, Qingqing Wu +2
This paper proposes a novel network framework of intelligent reflecting surface (IRS)-assisted simultaneous wireless information and power transfer (SWIPT) non-orthogonal multiple…
Intelligent Reflecting Surface (IRS)-Aided Covert Wireless Communications with Delay Constraint
Xiaobo Zhou, Shihao Yan, Qingqing Wu +2
This work examines the performance gain achieved by deploying an intelligent reflecting surface (IRS) in covert communications. To this end, we formulate the joint design of the tr…
Massive MIMO for Cellular-Connected UAV: Challenges and Promising Solutions
Yi Huang, Qingqing Wu, Rui Lu +2
Massive multiple-input multiple-output (MIMO) is a promising technology for enabling cellular-connected unmanned aerial vehicle (UAV) communications in the future. Equipped with fu…
