Hybrid Message Passing Algorithm for Downlink FDD Massive MIMO-OFDM Channel Estimation
Yi Song, Chuanzong Zhang, Xinhua Lu +2
The design of message passing (MP) algorithms on factor graphs is an effective manner to implement channel estimation (CE) in wireless communication systems, which performance can…
Efficient URLLC with a Reconfigurable Intelligent Surface and Imperfect Device Tracking
Fabio Saggese, Federico Chiariotti, Kimmo Kansanen +1
The use of Reconfigurable Intelligent Surfaces (RIS) technology to extend coverage and allow for better control of the wireless environment has been proposed in several use cases,…
Random Access Protocol with Channel Oracle Enabled by a Reconfigurable Intelligent Surface
Victor Croisfelt, Fabio Saggese, Israel Leyva-Mayorga +3
The widespread adoption of Reconfigurable Intelligent Surfaces (RISs) in future practical wireless systems is critically dependent on the integration of the RIS into higher-layer p…
A Random Access Protocol for RIS-Aided Wireless Communications
Victor Croisfelt, Fabio Saggese, Israel Leyva-Mayorga +3
Reconfigurable intelligent surfaces (RISs) are arrays of passive elements that can control the reflection of the incident electromagnetic waves. While RIS are particularly useful t…
