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…
Towards Standardizing Affine Frequency Division Multiplexing (AFDM) for Future Wireless Networks
Qu Luo, Lixia Xiao, Pei Xiao +6
Affine frequency division multiplexing~(AFDM) has emerged as a compelling waveform candidate for future wireless networks, owing to its strong resilience to doubly selective channe…
Joint Phase Noise and Off-Grid Channel Estimation for AFDM Systems via Sparse Bayesian Learning
You Xu, Huaijin Zhang, Lixia Xiao +2
In practical affine frequency division multiplexing (AFDM) systems, the intricate coupling of oscillator phase noise (PN) and off-grid fractional shifts traps conventional estimato…
Advanced Codebook Design for SCMA-aided NTNs With Randomly Distributed Users
Tianyang Hu, Qu Luo, Lixia Xiao +3
In this letter, a novel class of sparse codebooks is proposed for sparse code multiple access (SCMA) aided non-terrestrial networks (NTN) with randomly distributed users characteri…
Amplitude-Domain Reflection Modulation for Active RIS-Assisted Wireless Communications
Jing Zhu, Qu, Luo +5
In this paper, we propose a novel active reconfigurable intelligent surface (RIS)-assisted amplitude-domain reflection modulation (ADRM) transmission scheme, termed as ARIS-ADRM. T…
