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…
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…
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…
Bistatic Target Detection by Exploiting Both Deterministic Pilots and Unknown Random Data Payloads
Lei Xie, Fan Liu, Shenghui Song +1
Integrated sensing and communication (ISAC) plays a crucial role in 6G, to enable innovative applications such as drone surveillance, urban air mobility, and low-altitude logistics…
Sensing With Communication Signals: From Information Theory to Signal Processing
Fan Liu, Ya-Feng Liu, Yuanhao Cui +6
The Integrated Sensing and Communications (ISAC) paradigm is anticipated to be a cornerstone of the upcoming 6G networks. In order to optimize the use of wireless resources, 6G ISA…
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…
