Joint Chirp Parameter Selection and Low-Complexity MMSE Receiver Design for AFDM Systems
Ruiyuan Mao, Qu Luo, Jianguo Li +5
Affine frequency division multiplexing (AFDM) has emerged as a promising waveform against doubly selective channels under high-mobility communication scenarios. Optimal chirp param…
AFDM-FTN: A Spectrally Efficient Waveform for High-Mobility Communications
Xianle Dai, Qu Luo, Jianguo Li +4
The paper introduces AFDM-FTN, a waveform that combines affine frequency division multiplexing with faster‑than‑Nyquist signaling to boost spectral efficiency in high‑mobility wire…
Multi-Functional Chirp Signalling for Next-Generation Multi-Carrier Wireless Networks: Communications, Sensing and ISAC Perspectives
Zeping Sui, Qu Luo, Zilong Liu +6
To meet the increasingly demanding quality-of-service requirements of the next-generation multi-carrier mobile networks, it is essential to design multi-functional signalling schem…
Frame-Based AFDM-ISAC Waveform Design With Chirp-Enabled Pulse Compression
Qu Luo, Zilong Liu, Musavian Leila +3
This paper proposes an Affine frequency division multiplexing (AFDM)-empowered integrated sensing and communications (ISAC) design, referred to as AFDM-ISAC. We first design a nove…
Spatially Coupled Sparse Code Multiple Access (SC-SCMA): A Spectral Graph Approach
Yiming Gui, Zilong Liu, Qu Luo +1
This paper presents a spatially coupled sparse code multiple access (SC-SCMA) framework to overcome the performance and scalability limitations of conventional SCMA systems. By ana…
Beyond the RF Paradigm: Rydberg Atomic Receivers for Next-Generation IoT
Qihao Peng, Qu Luo, Dongnan Xia +11
Next-generation Internet-of-Things (IoT) is evolving toward a ubiquitous, ultra-low-power, and multi-band heterogeneous networking paradigm that seamlessly integrates terrestrial,…
