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…
On the Optimality of OFDM for Aperiodic Ranging
Yifeng Xiong, Fan Liu, Ya-Feng Liu +2
We study the expected aperiodic autocorrelation sidelobes of random communication symbols transmitted through a unitary modulation matrix. We consider proper sub-Gaussian constella…
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…
Relativistic Cramér-Rao Bound Scaling for Device-Based and Device-Free Sensing
Fan Liu, Yifeng Xiong, Weijie Yuan +3
This letter investigates range and velocity estimation under relativistic motion for device-based (DB) and device-free (DF) sensing. By deriving the exact time-scaling and time-shi…
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…
