协作式多智能超表面辅助的无线通信系统研究综述
A Survey on Collaborative Multi-RIS Assisted Wireless Communication Systems
摘要
Abstract
As a transformative technology,Reconfigurable Intelligent Surface(RIS)can intelligently reconfigure wireless environ-ments to enhance the data rate and reliability of wireless signal transmission.Although extensive research has been conducted on RIS-assisted wireless systems in existing literature,early studies primarily focused on systems where signals are reflected once by a single or multiple RISs.However,in complex environments,single-reflection RIS links are often prone to blockage by dense obstacles,severely limiting wireless coverage.To address this challenge,recent studies have proposed a novel collaborative multi-RIS system that leverages densely deployed RISs to establish rich cooperatively reflected Line-of-Sight(LOS)links,significantly extending the high-frequency cov-erage range.However,compared to traditional single-reflection RIS systems,collaborative multi-RIS systems face new challenges in de-ployment design,performance optimization,and channel acquisition.This paper reviews recent advances in collaborative multi-RIS sys-tems systematically,summarizing progress in deployment strategies,beamforming,and cooperative passive beam routing,channel estima-tion,and performance analysis,providing key references for future research in this field.关键词
