Channel Estimation By Transmitting Pilots From Reconfigurable Intelligent Surface
Yanze Zhu, Yang Liu, Qingqing Wu +2
Reconfigurable intelligent surface (RIS) is a promising technology for future wireless communication systems. Channel estimation (CE) of RIS device is a critical but also challengi…
Joint Activity Detection and Channel Estimation in Massive Machine-Type Communications with Low-Resolution ADC
Ye Xue, An Liu, Yang Li +2
In massive machine-type communications, data transmission is usually considered sporadic, and thus inherently has a sparse structure. This paper focuses on the joint activity detec…
Low-Complexity Channel Estimation for Massive MIMO Systems with Decentralized Baseband Processing
Yanqing Xu, Bo Wang, Enbin Song +2
The traditional centralized baseband processing architecture is faced with the bottlenecks of high computation complexity and excessive fronthaul communication, especially when the…
Quantized Federated Learning under Transmission Delay and Outage Constraints
Yanmeng Wang, Yanqing Xu, Qingjiang Shi +1
Federated learning (FL) has been recognized as a viable distributed learning paradigm which trains a machine learning model collaboratively with massive mobile devices in the wirel…
Iterative Algorithm Induced Deep-Unfolding Neural Networks: Precoding Design for Multiuser MIMO Systems
Qiyu Hu, Yunlong Cai, Qingjiang Shi +3
Optimization theory assisted algorithms have received great attention for precoding design in multiuser multiple-input multiple-output (MU-MIMO) systems. Although the resultant opt…
Efficiency Maximization for UAV-Enabled Mobile Relaying Systems with Laser Charging
Ming-Min Zhao, Qingjiang Shi, Min-Jian Zhao
This work studies the joint problem of power and trajectory optimization in an unmanned aerial vehicle (UAV)-enabled mobile relaying system. In the considered system, in order to p…
