Symbol-Level Precoding for MU-MIMO System with RIRC Receiver
Xiao Tong, Ang Li, Lei Lei +2
Consider a multiuser multiple-input multiple-output (MU-MIMO) downlink system in which the base station (BS) sends multiple data streams to multi-antenna users via symbol-level pre…
Adapting to Dynamic LEO-B5G Systems: Meta-Critic Learning Based Efficient Resource Scheduling
Yaxiong Yuan, Lei lei, Thang X. Vu +3
Low earth orbit (LEO) satellite-assisted communications have been considered as one of key elements in beyond 5G systems to provide wide coverage and cost-efficient data services.…
Joint Optimization of Beam-Hopping Design and NOMA-Assisted Transmission for Flexible Satellite Systems
Anyue Wang, Lei Lei, Eva Lagunas +3
Next-generation satellite systems require more flexibility in resource management such that available radio resources can be dynamically allocated to meet time-varying and non-unif…
An Overview of Generic Tools for Information-Theoretic Secrecy Performance Analysis over Wiretap Fading Channels
Long Kong, Yun Ai, Lei Lei +3
An alternative or supplementary approach named as physical layer security has been proposed to afford an extra security layer on top of the conventional cryptography technique. In…
NOMA-Enabled Multi-Beam Satellite Systems: Joint Optimization to Overcome Offered-Requested Data Mismatches
Anyue Wang, Lei Lei, Eva Lagunas +3
Non-Orthogonal Multiple Access (NOMA) has potentials to improve the performance of multi-beam satellite systems. The performance optimization in satellite-NOMA systems can be diffe…
Energy Minimization in UAV-Aided Networks: Actor-Critic Learning for Constrained Scheduling Optimization
Yaxiong Yuan, Lei Lei, Thang Xuan Vu +3
In unmanned aerial vehicle (UAV) applications, the UAV's limited energy supply and storage have triggered the development of intelligent energy-conserving scheduling solutions. In…
