Reconfigurable Intelligent Surfaces based RF Sensing: Design, Optimization, and Implementation
Jingzhi Hu, Hongliang Zhang, Boya Di +5
Using radio-frequency (RF) sensing techniques for human posture recognition has attracted growing interest due to its advantages of pervasiveness, contact-free observation, and pri…
Signal Design for AF Relay Systems using Superposition Coding and Finite-Alphabet Inputs
Bohai Li, He Chen, Zheng Dong +2
This paper focuses on the signal design in a Gaussian amplify-and-forward (AF) relay system with superposition coding (SC) being applied at the relay, which allows the source and r…
Minimizing Age of Information for Real-Time Monitoring in Resource-Constrained Industrial IoT Networks
Qian Wang, He Chen, Yonghui Li +2
This paper considers an Industrial Internet of Thing (IIoT) system with a source monitoring a dynamic process with randomly generated status updates. The status updates are sent to…
Hybrid Precoding Design for Reconfigurable Intelligent Surface aided mmWave Communication Systems
Chandan Pradhan, Ang Li, Lingyang Song +2
In this letter, we focus on the hybrid precoding (HP) design for the reconfigurable intelligent surface (RIS) aided multi-user (MU) millimeter wave (mmWave) communication systems.…
Multi-Antenna Aided Secrecy Beamforming Optimization for Wirelessly Powered HetNets
Shiqi Gong, Shaodan Ma, Chengwen Xing +2
The new paradigm of wirelessly powered two-tier heterogeneous networks (HetNets) is considered in this paper. Specifically, the femtocell base station (FBS) is powered by a power b…
Dynamic HARQ with Guaranteed Delay
Mahyar Shirvanimoghaddam, Hossein Khayami, Yonghui Li +1
In this paper, a dynamic-hybrid automatic repeat request (D-HARQ) scheme with guaranteed delay performance is proposed. As opposed to the conventional HARQ that the maximum number…
