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…
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…
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…
