Rotatable Antenna Enabled Multi-Satellite Communications: Joint Satellite Selection and Boresight Trajectory Optimization
Xingxiang Peng, Qingqing Wu, Haiying Hu +2
This paper considers a satellite-to-ground communication system in which a ground station (GS) equipped with independently rotatable antenna (RA) elements jointly decodes independe…
Rotatable Antenna Relaying: Joint Precoding and Antenna Pointing Design
Ying Gao, Qingqing Wu, Wen Chen
This paper investigates a rotatable antenna (RA)-enhanced half-duplex amplify-and-forward relaying system, where a multi-antenna base station (BS) serves multiple single-antenna us…
Beyond Beamforming: Phase-and-Gain Channel Shaping via Rotatable Antenna Arrays
Xingxiang Peng, Qingqing Wu, Ziyuan Zheng +2
This paper investigates geometry-reconfigurable transmission for multiuser communication systems enabled by a rotatable antenna array. In contrast to conventional fixed arrays, the…
Two-Scale Spatial Deployment for Cost-Effective Wireless Networks via Cooperative IRSs and Movable Antennas
Ying Gao, Qingqing Wu, Ziyuan Zheng +4
This paper proposes a two-scale spatial deployment strategy to ensure reliable coverage for multiple target areas, integrating macroscopic intelligent reflecting surfaces (IRSs) an…
Cell-Free MIMO with Rotatable Antennas: When Macro-Diversity Meets Antenna Directivity
Xingxiang Peng, Qingqing Wu, Ziyuan Zheng +5
Cell-free networks leverage distributed access points (APs) to achieve macro-diversity, yet their performance is often constrained by large disparities in channel quality arising f…
