Active RIS-Assisted MIMO System for Vital Signs Extraction: ISAC Modeling, Deep Learning, and Prototype Measurements
De-Ming Chian, Chao-Kai Wen, Feng-Ji Chen +2
We present the RIS-VSign system, an active reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) f…
Low-Communication Resilient Distributed Estimation Algorithm Based on Memory Mechanism
Wei Li, Limei Hu, Feng Chen +1
In multi-task adversarial networks, the accurate estimation of unknown parameters in a distributed algorithm is hindered by attacked nodes or links. To tackle this challenge, this…
Hybrid Near-Far Field 6D Movable Antenna Design Exploiting Directional Sparsity and Deep Learning
Xiaodan Shao, Limei Hu, Yulong Sun +7
Six-dimensional movable antenna (6DMA) has been identified as a new disruptive technology for future wireless systems to support a large number of users with only a few antennas. H…
Experimental Evaluation of Multiple Active RISs for 5G MIMO Commercial Networks
Feng-Ji Chen, Chao-Kai Wen, De-Ming Chian
While numerous experimental studies have demonstrated the feasibility of reconfigurable intelligent surface (RIS) technology, most have primarily focused on extending coverage. In…
