DFT-s-OFDM with Chirp Modulation
Yujie Liu, Yong Liang Guan, David González G. +1
In this paper, a new waveform called discrete Fourier transform spread orthogonal frequency division multiplexing with chirp modulation (DFT-s-OFDM-CM) is proposed for the next gen…

Local Ambiguity Shaping for Doppler-Resilient Sequences Under Spectral and PAPR Constraints
Shi He, Lingsheng Meng, Yao Ge +3
This paper focuses on designing Doppler-resilient sequences with low local Ambiguity Function (AF) sidelobes, subject to certain spectral and Peak-to-Average Power Ratio (PAPR) con…

A Novel Angle-Delay-Doppler Estimation Scheme for AFDM-ISAC System in Mixed Near-field and Far-field Scenarios
Yirui Luo, Yong Liang Guan, Yao Ge +2
The recently proposed multi-chirp waveform, affine frequency division multiplexing (AFDM), is considered as a potential candidate for integrated sensing and communication (ISAC). H…
