Multi-Carrier NOMA-Empowered Wireless Federated Learning with Optimal Power and Bandwidth Allocation
Weicai Li, Tiejun Lv, Yashuai Cao +2
Wireless federated learning (WFL) undergoes a communication bottleneck in uplink, limiting the number of users that can upload their local models in each global aggregation round.…
Two-Timescale Optimization for Intelligent Reflecting Surface-Assisted MIMO Transmission in Fast-Changing Channels
Yashuai Cao, Tiejun Lv, Wei Ni
The application of intelligent reflecting surface (IRS) depends on the knowledge of channel state information (CSI), and has been hindered by the heavy overhead of channel training…
Downlink Power Minimization in Intelligent Reconfigurable Surface-Aided Security Classification Wireless Communications System
Jintao Xing, Tiejun Lv, Yashuai Cao +2
User privacy protection is considered a critical issue in wireless networks, which drives the demand for various secure information interaction techniques. In this paper, we introd…
Low-Complexity Distributed Precoding in User-Centric Cell-Free mmWave MIMO Systems
Yingrong Zhong, Yashuai Cao, Tiejun Lv
User-centric (UC) based cell-free (CF) structures can provide the benefits of coverage enhancement for millimeter wave (mmWave) multiple input multiple output (MIMO) systems, which…
Sum-Rate Maximization for Multi-Reconfigurable Intelligent Surface-Assisted Device-to-Device Communications
Yashuai Cao, Tiejun Lv, Wei Ni +1
This paper proposes to deploy multiple reconfigurable intelligent surfaces (RISs) in device-to-device (D2D)-underlaid cellular systems. The uplink sum-rate of the system is maximiz…
