Beyond Beamforming: Phase-and-Gain Channel Shaping via Rotatable Antenna Arrays
Xingxiang Peng, Qingqing Wu, Ziyuan Zheng, Wen Chen, Guangchi Zhang
This paper investigates geometry-reconfigurable transmission for multiuser communication systems enabled by a rotatable antenna array. In contrast to conventional fixed arrays, the proposed architecture jointly exploits array pose adjustment and element-level boresight steering,…
