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…
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…
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…
On Discrete Ambiguity Functions of Random Communication Waveforms
Ying Zhang, Fan Liu, Yifeng Xiong +6
This paper provides a fundamental characterization of the discrete ambiguity functions (AFs) of random communication waveforms under arbitrary orthonormal modulation with random co…
Adaptive Matched Filtering for Sensing With Communication Signals in Cluttered Environments
Lei Xie, Hengtao He, Yifeng Xiong +2
This paper investigates the performance of the adaptive matched filtering (AMF) in cluttered environments, particularly when operating with superimposed signals. Since the instanta…
