Enabling Cooperative Hybrid Beamforming in TDD-based Distributed MIMO Systems

open access: yes, 2023
Distributed massive MIMO networks are envisioned to realize cooperative multi-point transmission in next-generation wireless systems. For efficient cooperative hybrid beamforming, the cluster of access points (APs) needs to obtain precise estimates of ...

Movable Antennas-Assisted Secure Transmission for Cooperative Wireless Communication

open access: yesIEEE Open Journal of the Communications Society
Wireless communication is vulnerable to deep fading and eavesdropping, especially in long-distance double-hop scenarios. To address these issues, this paper proposes the movable antenna (MA)-assisted secure transmission scheme.
