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)…
Some Optimal and Near Optimal Doppler Resilient Complementary Sequence Sets
Bingsheng Shen, Zhengchun Zhou, Yang Yang +1
Sequences with excellent ambiguity functions are very useful in radar detection and modern mobile communications. Doppler resilient complementary sequence (DRCS) is a new type of s…
Doppler Resilient Complementary Sequences: Tighter Aperiodic Ambiguity Function Bound and Optimal Constructions
Zheng Wang, Yang Yang, Zhengchun Zhou +2
Doppler-resilient complementary sequence sets (DRCSs) are crucial in modern communication and sensing systems in mobile environments. In this paper, we propose a new lower bound fo…
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…
Zak-Transform-Induced Optimal Sequences and Their Applications in OTFS
Xiuping Peng, Congying Wu, Zilong Liu +4
This paper introduces a novel finite Zak transform (FZT)-aided framework for constructing multiple zero-correlation zone (ZCZ) sequence sets with optimal correlation properties. Sp…
