AoA-Based Pilot Assignment in Massive MIMO Systems Using Deep Reinforcement Learning
Yasaman Omid, Seyed MohammadReza Hosseini, Seyyed MohammadMahdi Shahabi +2
In this paper, the problem of pilot contamination in a multi-cell massive multiple input multiple output (M-MIMO) system is addressed using deep reinforcement learning (DRL). To th…
Beamforming Design for Multiuser Transmission Through Reconfigurable Intelligent Surface
Zhaohui Yang, Wei Xu, Chongwen Huang +2
This paper investigates the problem of resource allocation for multiuser communication networks with a reconfigurable intelligent surface (RIS)-assisted wireless transmitter. In th…
Delay Minimization for Federated Learning Over Wireless Communication Networks
Zhaohui Yang, Mingzhe Chen, Walid Saad +4
In this paper, the problem of delay minimization for federated learning (FL) over wireless communication networks is investigated. In the considered model, each user exploits limit…

Hui Long, Ming Chen, Zhaohui Yang +4
This paper investigates the problem of secure energy efficiency maximization for a reconfigurable intelligent surface (RIS) assisted uplink wireless communication system, where an…
Cooperative Rate-Splitting for Secrecy Sum-Rate Enhancement in Multi-antenna Broadcast Channels
Ping Li, Ming Chen, Yijie Mao +3
In this paper, we employ Cooperative Rate-Splitting (CRS) technique to enhance the Secrecy Sum Rate (SSR) for the Multiple Input Single Output (MISO) Broadcast Channel (BC), consis…
A Priority-Based Cross-Layer Design for Future VANETs through Full-Duplex Technology
Junwei Zang, Vahid Towhidlou, Mohammad Shikh-Bahaei
Among all requirements for vehicle-to-everything (V2X) communications, successful delivery of packets with small delay is of the highest significance. Especially, the delivery of a…
