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…
