Wireless Imaging for Low-Altitude Surveillance: A New Paradigm for ISAC Networks
Yixuan Huang, Jie Yang, Chao-Kai Wen +1
The rapid growth of the low-altitude economy calls for integrated sensing and communication (ISAC) networks capable of robust flight monitoring. This article advocates wireless ima…
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…
Multi-Modal Environment-Aware Beam Management for Massive MIMO: A Geometry-Driven Virtual Base Station Framework
Yijie Bian, Wei Guo, Jie Yang +4
High-frequency massive multiple-input multiple-output (MIMO) systems promise ultra-high data rates. However, efficient beam management remains challenging due to the prohibitive be…
SkySense: A Semi-Supervised Generative Framework for UAV Localization in ISAC Networks
Shenghan Luo, Yin Xu, Jie Yang +4
Extreme data scarcity and inherent multipath spatial ambiguity severely limit existing deep learning-based channel state information (CSI) fingerprinting localization schemes for t…
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…
