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…
Towards Power-Efficient Aerial Communications via Dynamic Multi-UAV Cooperation
Lin Xiang, Lei Lei, Symeon Chatzinotas +2
Aerial base stations (BSs) attached to unmanned aerial vehicles (UAVs) constitute a new paradigm for next-generation cellular communications. However, the flight range and communic…
A Framework for Optimizing Multi-cell NOMA: Delivering Demand with Less Resource
Lei You, Lei Lei, Di Yuan +3
Non-orthogonal multiple access (NOMA) allows multiple users to simultaneously access the same time-frequency resource by using superposition coding and successive interference canc…
