Low-overhead Beam Training Scheme for Extremely Large-Scale RIS in Near-field
Wang Liu, Cunhua Pan, Hong Ren +3
Extremely large-scale reconfigurable intelligent surface (XL-RIS) has recently been proposed and is recognized as a promising technology that can further enhance the capacity of co…
Two-Timescale Transmission Design for Wireless Communication Systems Aided by Active RIS
Zhangjie Peng, Tianshu Li, Cunhua Pan +2
This paper considers an active reconfigurable intelligent surface (RIS)-aided communication system, where an M-antenna base station (BS) transmits data symbols to a single-antenna…
When Physical Layer Key Generation Meets RIS: Opportunities, Challenges, and Road Ahead
Ning Gao, Yu Han, Nannan Li +2
Physical layer key generation (PLKG) is a promising technology to obtain symmetric keys between a pair of wireless communication users in a plug-and-play manner. The shared entropy…
Weighted MMSE Precoding for Constructive Interference Region
Yafei Wang, Wenjin Wang, Li You +2
In this paper, we propose a symbol-level precoding (SLP) design that aims to minimize the weighted mean square error between the received signal and the constellation point located…
Overview of Deep Learning-based CSI Feedback in Massive MIMO Systems
Jiajia Guo, Chao-Kai Wen, Shi Jin +1
Many performance gains achieved by massive multiple-input and multiple-output depend on the accuracy of the downlink channel state information (CSI) at the transmitter (base statio…
Model-Driven Deep Learning-Based MIMO-OFDM Detector: Design, Simulation, and Experimental Results
Xingyu Zhou, Jing Zhang, Chen-Wei Syu +3
Multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM), a fundamental transmission scheme, promises high throughput and robustness against multipath…
