Security in Low-Altitude ISAC with Coupled Communication and Sensing Information Leakage
Meiding Liu, Yuyuan Fang, Zhengchun Zhou +2
Secure information transmission in integrated sensing and communication (ISAC) systems deployed in low-altitude wireless networks (LAWN) is particularly challenging due to the open…
Priority Random Access and Power Control for NOMA-ALOHA in Heterogeneous mMTC
Wenbo Fan, Pingzhi Fan, Zilong Liu
This paper presents a novel priority random access (PRA) non-orthogonal multiple access assisted ALOHA, called PRA-NA, to provide access priority for machine-type devices (MTDs) wi…
Enabling Flexible AFDM-ISAC Design: When Ambiguity Shaping Meets PAPR Control
Lingsheng Meng, Yong Liang Guan, Zilong Liu +2
Affine frequency division multiplexing (AFDM) has emerged as an enabling waveform for integrated sensing and communication (ISAC) due to its intrinsic chirp signaling nature. Never…
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

Matched Filtering-Based Channel Estimation for AFDM Systems in Doubly Selective Channels
Xiangjun Li, Zilong Liu, Zhengchun Zhou +1
Affine frequency division multiplexing (AFDM) has recently emerged as an excellent backward-compatible 6G waveform. In this paper, we study matched filtering (MF) assisted channel…
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…
