Radar-enabled ambient backscatter communications
Luca Venturino, Emanuele Grossi, Marco Lops +2
In this work, we exploit the radar clutter (i.e., the ensemble of echoes generated by the terrain and/or the surrounding objects in response to the signal emitted by a radar transm…
Privacy-preserving Channel Estimation in Cell-free Hybrid Massive MIMO Systems
Jun Xu, Xiaodong Wang, Pengcheng Zhu +1
We consider a cell-free hybrid massive multiple-input multiple-output (MIMO) system with users and access points (APs), each with antennas and radio freque…
Unfolded Deep Neural Network (UDNN) for High Mobility Channel Estimation
Yinchuan Li, Xiaodong Wang, Robert L. Olesen
High mobility channel estimation is crucial for beyond 5G (B5G) or 6G wireless communication networks. This paper is concerned with channel estimation of high mobility OFDM communi…
ADMM-Net for Communication Interference Removal in Stepped-Frequency Radar
Jeremy Johnston, Yinchuan Li, Marco Lops +1
Complex ADMM-Net, a complex-valued neural network architecture inspired by the alternating direction method of multipliers (ADMM), is designed for interference removal in super-res…
Multi-mode OAM Radio Waves: Generation, Angle of Arrival Estimation and Reception With UCAs
Rui Chen, Wen-Xuan Long, Xiaodong Wang +1
Orbital angular momentum (OAM) at radio frequency (RF) provides a novel approach of multiplexing a set of orthogonal modes on the same frequency channel to achieve high spectrum ef…
mmWave/THz Channel Estimation Using Frequency-Selective Atomic Norm Minimization
Yicheng Xu, Hongyun Chu, Xiaodong Wang
We propose a MIMO channel estimation method for millimeter-wave (mmWave) and terahertz (THz) systems based on frequency-selective atomic norm minimization (FS-ANM). For the strong…
