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…
