Pilot Design and Signal Detection for Symbiotic Radio over OFDM Carriers
Hao Chen, Qianqian Zhang, Ruizhe Long +2
Symbiotic radio (SR) is a promising solution to achieve high spectrum- and energy-efficiency due to its spectrum sharing and low-power consumption properties, in which the secondar…
Assistance-Transmission Tradeoff for RIS-assisted Symbiotic Radios
Hu Zhou, Qianqian Zhang, Ying-Chang Liang +1
This paper studies the reconfigurable intelligent surface (RIS)-assisted symbiotic radio (SR) system, where an RIS acts as a secondary transmitter to transmit its information by le…
Modulation Design and Optimization for RIS-Assisted Symbiotic Radios
Hu Zhou, Bowen Cai, Qianqian Zhang +3
In reconfigurable intelligent surface (RIS)-assisted symbiotic radio (SR), the RIS acts as a secondary transmitter by modulating its information bits over the incident primary sign…
Active Reconfigurable Intelligent Surface Aided Wireless Communications
Ruizhe Long, Ying-Chang Liang, Yiyang Pei +1
Reconfigurable Intelligent Surface (RIS) is a promising solution to reconfigure the wireless environment in a controllable way. To compensate for the double-fading attenuation in t…
Modulation in the Air: Backscatter Communication over Ambient OFDM Carrier
Gang Yang, Ying-Chang Liang, Rui Zhang +1
Ambient backscatter communication (AmBC) enables radio-frequency (RF) powered backscatter devices (BDs) (e.g., sensors, tags) to modulate their information bits over ambient RF car…
