Active RIS-Assisted MIMO-OFDM System: Analyses and Prototype Measurements
De-Ming Chian, Feng-Ji Chen, Yu-Chen Chang +5
In this study, we develop an active reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) prototyp…
Analytical Characterization of Coverage Regions for STAR-RIS-aided NOMA/OMA Communication Systems
Farshad Rostami Ghadi, F. Javier Lopez-Martinez, Kai-Kit Wong
We provide an analytical characterization of the coverage region of simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS)-aided two-user downlink…
A Novel Channel Model for Reconfigurable Intelligent Surfaces with Consideration of Polarization and Switch Impairments
De-Ming Chian, Chao-Kai Wen, Chi-Hung Wu +2
Future wireless networks require the ability to actively adjust the wireless environment to meet strict performance indicators. Reconfigurable Intelligent Surface (RIS) technology…
Deep Learning Based Predictive Beamforming Design
Juping Zhang, Gan Zheng, Yangyishi Zhang +2
This paper investigates deep learning techniques to predict transmit beamforming based on only historical channel data without current channel information in the multiuser multiple…
Intelligent Omni Surface-Assisted Self-Interference Cancellation for Full-Duplex MISO System
Sisai Fang, Gaojie Chen, Pei Xiao +2
The full-duplex (FD) communication can achieve higher spectrum efficiency than conventional half-duplex (HD) communication; however, self-interference (SI) is the key hurdle. This…
Beyond Transmitting Bits: Context, Semantics, and Task-Oriented Communications
Deniz Gunduz, Zhijin Qin, Inaki Estella Aguerri +5
Communication systems to date primarily aim at reliably communicating bit sequences. Such an approach provides efficient engineering designs that are agnostic to the meanings of th…
