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…
New Spectrally Constrained Sequence Sets with Optimal {Periodic} Cross-Correlation
Zhifan Ye, Zhengchun Zhou, Zilong Liu +2
Spectrally constrained sequences (SCSs) play an important role in modern communication and radar systems operating over non-contiguous spectrum. Despite numerous research attempts…
Low Ambiguity Zone: Theoretical Bounds and Doppler-Resilient Sequence Design in Integrated Sensing and Communication Systems
Zhifan Ye, Zhengchun Zhou, Pingzhi Fan +3
In radar sensing and communications, designing Doppler resilient sequences (DRSs) with low ambiguity function for delay over the entire signal duration and Doppler shift over the e…
HpGAN: Sequence Search with Generative Adversarial Networks
Mingxing Zhang, Zhengchun Zhou, Lanping Li +3
Sequences play an important role in many engineering applications and systems. Searching sequences with desired properties has long been an interesting but also challenging researc…
Symmetrical Z-Complementary Code Sets (SZCCSs) for Optimal Training in Generalized Spatial Modulation
Yajing Zhou, Zhengchun Zhou, Zilong Liu +3
This paper introduces a novel class of code sets, called "symmetrical Z-complementary code sets (SZCCSs)" , whose aperiodic auto- and cross- correlation sums exhibit zero-correlati…
Sharp Sufficient Conditions for Stable Recovery of Block Sparse Signals by Block Orthogonal Matching Pursuit
Jinming Wen, Zhengchun Zhou, Zilong Liu +2
In this paper, we use the block orthogonal matching pursuit (BOMP) algorithm to recover block sparse signals $\x$ from measurements $\y=\A\x+\v$, where $\v$ is an -bounded…
