Joint Chirp Parameter Selection and Low-Complexity MMSE Receiver Design for AFDM Systems

Ruiyuan Mao, Qu Luo, Jianguo Li, Fabien Héliot, Tianqi Mao, Pei Xiao, et al.

Affine frequency division multiplexing (AFDM) has emerged as a promising waveform against doubly selective channels under high-mobility communication scenarios. Optimal chirp parameter selection and reduced-complexity receiver design in AFDM are essential for achieving satisfacto…

AFDM-FTN: A Spectrally Efficient Waveform for High-Mobility Communications

Xianle Dai, Qu Luo, Jianguo Li, Fabien Heliot, Shuangyang Li, Lixia Xiao, et al.

This paper proposes an affine frequency division multiplexing (AFDM)-aided faster-than-Nyquist (FTN) waveform, termed AFDM-FTN, to enhance spectral efficiency (SE) in high-mobility communication scenarios. We first derive the AFDM-FTN input-output relationship and analyze the FTN…

Two-Stage Multi-Modal Fusion with Adaptive Alignment for Action Quality Assessment

Kanglei Zhou, Ruizhi Cai, Xinning Wang, Yijian Zheng, Liyuan Wang, Jianguo Li, et al.

Action Quality Assessment (AQA) aims to evaluate how well a person performs a movement, which is essential in applications such as sports scoring, skill assessment, and healthcare. However, unimodal approaches often struggle to capture subtle cues of movement quality in real-worl…
