Orthogonal Chirp Delay-Doppler Division Multiplexing (CDDM) Modulation for High Mobility Communications
Chaoyuan Bai, Pingzhi Fan, Zhengchun Zhou +1
This paper proposes a novel multi-carrier modulation framework for high-mobility communication scenarios. Our key idea lies in spreading data symbols across the delay-Doppler (DD)…

Waveform and Filter Design for Integrated Sensing and Communication Against Signal-dependent Modulated Jamming
Yu Zhou, Qiao Shi, Zhengchun Zhou +2
This paper focuses on an integrated sensing and communication (ISAC) system in the presence of signal-dependent modulated jamming (SDMJ). Our goal is to suppress jamming while carr…

Grid Evolution for Doubly Fractional Channel Estimation in OTFS Systems
Xiangjun Li, Pingzhi Fan, Qianli Wang +1
In orthogonal time-frequency space communications, the performances of existing on-grid and off-grid channel estimation (CE) schemes are determined by the delay-Doppler (DD) grid d…
