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…
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…
Low-Altitude ISAC with Rotatable Active and Passive Arrays
Ziyuan Zheng, Qingqing Wu, Yanze Zhu +4
This paper investigates a low-altitude integrated sensing and communication (ISAC) system that leverages cooperative rotatable active and passive arrays. We consider a downlink sce…
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…
Rethinking Soft Interference Cancellation (IC) for MIMO: A Hard-Decision IC Inspired Recursive Scheme
Yanze Zhu, Hufei Zhu, Qingqing Wu +3
Multiple-input multiple-output (MIMO) technology has been regarded as one of the most important technologies to enable emerging applications in current and next generation wireless…
On Efficient V-BLAST Detection: Recursive and Hybrid Schemes
