SNR-Dependent Mismatched Filtering for Bistatic OFDM Ranging
Ying Zhang, Fan Liu, Yifeng Xiong +3
This paper investigates the ranging performance of a bistatic integrated sensing and communications (ISAC) system employing orthogonal frequency-division multiplexing (OFDM), in wh…
Ambiguity Function Analysis of Pilot-Embedded Random OFDM Signals
Jialin Wu, Fan Liu, Ying Zhang +3
This paper investigates the statistical ambiguity functions (AFs) of orthogonal frequency division multiplexing (OFDM) waveforms that incorporate deterministic unit-modulus pilot s…
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…
How Much Sensing Information Is Needed to Control an Unstable Linear System?
Ming Li, Fan Liu, Yifeng Xiong +4
Modern control systems increasingly rely on sensing to infer the system state before control actions can be taken. Yet a given observation mechanism may fail to preserve sufficient…
Sensing-Limited Control of Noiseless Linear Systems Under Nonlinear Observations
Ming Li, Fan Liu, Yifeng Xiong +2
This paper investigates the fundamental information-theoretic limits for the control and sensing of noiseless linear dynamical systems subject to a broad class of nonlinear observa…
CP-OFDM Achieves Lower Ranging CRB Than Frequency-Spread Waveforms in the Large-Sample Regime
Fan Liu, Yifeng Xiong, Ya-Feng Liu +3
The inherent randomness of communication symbols creates a fundamental tension in Integrated Sensing and Communications (ISAC). On the one hand, they enable data transmission while…
