Massive MIMO-OTFS-Based Random Access for Cooperative LEO Satellite Constellations
Boxiao Shen, Yongpeng Wu, Shiqi Gong +3
This paper investigates joint device identification, channel estimation, and symbol detection for cooperative multi-satellite-enhanced random access, where orthogonal time-frequenc…
Integrated Communications and Localization for Massive MIMO LEO Satellite Systems
Li You, Xiaoyu Qiang, Yongxiang Zhu +6
Integrated communications and localization (ICAL) will play an important part in future sixth generation (6G) networks for the realization of Internet of Everything (IoE) to suppor…
Random Aggregate Beamforming for Over-the-Air Federated Learning in Large-Scale Networks
Chunmei Xu, Shengheng Liu, Yongming Huang +2
At present, there is a trend to deploy ubiquitous artificial intelligence (AI) applications at the edge of the network. As a promising framework that enables secure edge intelligen…
Perpetual Reconfigurable Intelligent Surfaces Through In-Band Energy Harvesting: Architectures, Protocols, and Challenges
Konstantinos Ntontin, Alexandros-Apostolos A. Boulogeorgos, Sergi Abadal +3
Reconfigurable intelligent surfaces (RISs) are considered to be a key enabler of highly energy-efficient 6G and beyond networks. This property arises from the absence of power ampl…
