How Does Probabilistic Constellation Shaping Control Ranging Sidelobe Levels in ISAC?
Zexuan Jing, Yifeng Xiong, Fan Liu +2
Probabilistic constellation shaping (PCS), originally designed to fill the gap between finite uniform constellations and continuous capacity-achieving input distributions, has rece…
Exact Degrees of Freedom of Spatially Sparse MIMO Channels Without Prior CSI
Yifeng Xiong, Weijiang Zhao, Fan Liu +2
We characterize the degree of freedom (DoF) of a point-to-point blockwise memoryless channel without prior channel state information (CSI), with a fixed number of propagation p…
Auto-correlation Function Keying
Weijiang Zhao, Yifeng Xiong, Fan Liu +3
We propose ACFK: Auto-correlation Function Keying, a new integrated sensing and communication (ISAC) waveform that carries random communication data while directly controlling the…
Faster-than-Nyquist Signaling is Good for Single-Carrier ISAC: An Analytical Study
Shuangyang Li, Fan Liu, Yifeng Xiong +4
In this paper, we provide an analytical study of single-carrier faster-than-Nyquist (FTN) signaling for integrated sensing and communications (ISAC). Our derivations show that FTN…
Simultaneous Sensing Data Acquisition and Sharing in Low-Altitude Wireless Networks: Fundamental Limits and Optimal Signaling
Fuwang Dong, Fan Liu, Yifeng Xiong +3
In the low-altitude wireless networks, the simultaneous sensing data acquisition and sharing (SDAS) through an ISAC signaling strategy becomes a typical application scenario. In th…
Secure ISAC MIMO Systems: Exploiting Interference With Bayesian Cramér-Rao Bound Optimization
Nanchi Su, Fan Liu, Christos Masouros +3
In this paper, we present a signaling design for secure integrated sensing and communication (ISAC) systems comprising a dual-functional multi-input multi-output (MIMO) base statio…
Random ISAC Signals Deserve Dedicated Precoding
Shihang Lu, Fan Liu, Fuwang Dong +4
Radar systems typically employ well-designed deterministic signals for target sensing, while integrated sensing and communications (ISAC) systems have to adopt random signals to co…
From Torch to Projector: Fundamental Tradeoff of Integrated Sensing and Communications
Yifeng Xiong, Fan Liu, Kai Wan +3
Sensing and communications (S&C) have been historically developed in parallel. In recent decade, they have been evolving from separation to integration, giving rise to the integrat…
