Leveraging Location Information for RIS-aided mmWave MIMO Communications
Jiguang He, Henk Wymeersch, Markku Juntti
Location information offered by external positioning systems, e.g., satellite navigation, can be used as prior information in the process of beam alignment and channel parameter es…
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…
Channel Modeling and Performance Analysis of Airplane-Satellite Terahertz Band Communications
J. Kokkoniemi, J. M. Jornet, V. Petrov +2
Wireless connectivity in airplanes is becoming more important, demanded, and common. One of the largest bottlenecks with the in-flight Internet is that the airplane is far away fro…
Channel Estimation for RIS-Aided mmWave MIMO Systems via Atomic Norm Minimization
Jiguang He, Henk Wymeersch, Markku Juntti
A reconfigurable intelligent surface (RIS) can shape the radio propagation environment by virtue of changing the impinging electromagnetic waves towards any desired directions, thu…
Decision Triggered Data Transmission and Collection in Industrial Internet of Things
Jiguang He, Long Kong, Tero Frondelius +2
We propose a decision triggered data transmission and collection (DTDTC) protocol for condition monitoring and anomaly detection in the industrial Internet of things (IIoT). In the…
Channel Estimation for RIS-Aided mmWave MIMO Channels
Jiguang He, Markus Leinonen, Henk Wymeersch +1
A reconfigurable intelligent surface (RIS) can shape the radio propagation by passively changing the directions of impinging electromagnetic waves. The optimal control of the RIS r…
