An Optical Pathway to Movable Rydberg Atomic Quantum Receivers
Qihao Peng, Qu Luo, Lixia Xiao +6
This paper develops an optically movable Rydberg atomic quantum receiver (RAQR), in which the probe and coupling beams are steered within each vapor cell to dynamically reconfigure…
From Active to Battery-Free: Rydberg Atomic Quantum Receivers for Self-Sustained SWIPT-MIMO Networks
Qihao Peng, Qu Luo, Zheng Chu +5
In this paper, we proposed a hybrid simultaneous wireless information and power transfer (SWIPT)-enabled multiple-input multiple-output (MIMO) architecture, where the base station…
Cooperative Base Station Assignment and Resource Allocation for 6G ISAC Network
Jiajia Liao, Luping Xiang, Shida Zhong +3
In the upcoming 6G networks, integrated sensing and communications (ISAC) will be able to provide a performance boost in both perception and wireless connectivity. This paper consi…
DAFT-Spread Affine Frequency Division Multiple Access for Downlink Transmission
Yiwei Tao, Miaowen Wen, Yao Ge +3
Affine frequency division multiplexing (AFDM) and orthogonal AFDM access (O-AFDMA) are promising techniques based on chirp signals, which are able to suppress the performance deter…
Channel Estimation for AFDM With Superimposed Pilots
Kai Zheng, Miaowen Wen, Tianqi Mao +2
The recent proposed affine frequency division multiplexing (AFDM) employing a multi-chirp waveform has shown its reliability and robustness in doubly selective fading channels. In…
