Channel Estimation and Training Design for Active RIS Aided Wireless Communications

no code implementations6 Nov 2023 Hao Chen, Nanxi Li, Ruizhe Long, Ying-Chang Liang

To address this issue, we further investigate this ARIS-specific channel estimation problem and propose a least-square (LS) based channel estimator, whose performance can be further improved with the design on ARIS reflection patterns at the channel training phase.

Movable Antenna-Empowered AirComp

no code implementations22 Sep 2023 Zhenqiao Cheng, Nanxi Li, Jianchi Zhu, Xiaoming She, Chongjun Ouyang, Peng Chen

A novel over-the-air computation (AirComp) framework, empowered by the incorporation of movable antennas (MAs), is proposed to significantly enhance computation accuracy.
