Low-Complexity Near-Field Channel Estimation for Hybrid RIS Assisted Systems
Rafaela Schroeder, Jiguang He, Hamza Djelouat +1
We investigate the channel estimation (CE) problem for hybrid RIS assisted systems and focus on the near-field (NF) regime. Different from their far-field counterparts, NF channels…
Two-Stage Channel Estimation for Hybrid RIS Assisted MIMO Systems
Rafaela Schroeder, Jiguang He, Glauber Brante +1
Reconfigurable intelligent surfaces (RISs) have been proposed as a key enabler to improve the coverage of the signals and mitigate the frequent blockages in millimeter wave (mmWave…
Channel Estimation for Hybrid RIS Aided MIMO Communications via Atomic Norm Minimization
Rafaela Schroeder, Jiguang He, Markku Juntti
Reconfigurable intelligent surfaces (RISs) have been introduced as a remedy for mitigating frequent blockages in millimeter wave (mmWave) multiple-input multiple-output (MIMO) comm…
Channel Estimation and Hybrid Architectures for RIS-Assisted Communications
Jiguang He, Nhan Thanh Nguyen, Rafaela Schroeder +3
Reconfigurable intelligent surfaces (RISs) are considered as potential technologies for the upcoming sixth-generation (6G) wireless communication system. Various benefits brought b…
Passive RIS vs.Hybrid RIS: A Comparative Study on Channel Estimation
Rafaela Schroeder, Jiguang He, Markku Juntti
The reconfigurable intelligent surface (RIS) plays an important role in maintaining the connectivity in millimeter wave (mmWave) MIMO systems when the direct channel between the tr…
