A Low-Complexity Message-Passing Receiver for FTN-WAFT under Nonlinear Distortion
Xianle Dai, Qu Luo, Jianguo Li +4
This letter proposes a faster-than-Nyquist (FTN) weighted affine Fourier transform (WAFT) transmission scheme, termed FTN-WAFT, which combines the peak-to-average power ratio (PAPR…

AFDM-FTN: A Spectrally Efficient Waveform for High-Mobility Communications
Xianle Dai, Qu Luo, Jianguo Li +4
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…
