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.…
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…
Computation Offloading for IoT in C-RAN: Optimization and Deep Learning
Chandan Pradhan, Ang Li, Changyang She +2
We consider computation offloading for Internet-of-things (IoT) applications in multiple-input-multiple-output (MIMO) cloud-radio-access-network (C-RAN). Due to the limited battery…
On the Age of Information of Short-Packet Communications with Packet Management
Rui Wang, Yifan Gu, He Chen +2
In this paper, we consider a point-to-point wireless communication system. The source monitors a physical process and generates status update packets according to a Poisson process…
