Polarization-Aware Rotatable Antennas for RIS-Empowered Symbiotic Radios
Chao Zhang, Ruizhe Long, Boon-Hee Soong +1
This paper investigates a dual-polarized reconfigurable intelligent surface (DP-RIS)-empowered symbiotic radio (SR) system with rotatable antennas (RAs). By reconfiguring antenna o…
Simultaneous Indoor and Outdoor Coverage with Conformal Intelligent Omni-Surface
Yiqi Chen, Xiaoming She, Jianchi Zhu +3
Seamless indoor--outdoor coverage conventionally relies on coordinated outdoor macro cells and indoor small cells, incurring high deployment and backhaul costs. Intelligent omni-su…
Polarization-aware Reconfigurable Antenna Aided Wireless Communications
Chao Zhang, Hu Zhou, Ruizhe Long +2
Reconfigurable antennas (RAs) have emerged as a promising technology for future wireless networks, offering additional flexibility for wireless communications. Among existing desig…
Hierarchical Cognitive Spectrum Sharing in Space-Air-Ground Integrated Networks
Zizhen Zhou, Qianqian Zhang, Jungang Ge +1
In space-air-ground integrated networks (SAGINs), cognitive spectrum sharing has been regarded as a promising solution to improve spectrum efficiency by enabling a secondary networ…
Reconfigurable Intelligent Surface Assisted MIMO Symbiotic Radio Networks
Qianqian Zhang, Ying-Chang Liang, H. Vincent Poor
In this paper, a novel reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output (MIMO) symbiotic radio (SR) system is proposed, in which an RIS, operating a…
