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…
Multi-dimensional Spectral Super-Resolution with Prior Knowledge via Frequency-Selective Vandermonde Decomposition and ADMM
Yinchuan Li, Xiaodong Wang, Zegang Ding
This paper is concerned with estimation of multiple frequencies from incomplete and/or noisy samples based on a low-CP-rank tensor data model where each CP vector is an array respo…
Compressive Multidimensional Harmonic Retrieval with Prior Knowledge
Yinchuan Li, Xu Zhang, Zegang Ding +1
This paper concerns the problem of estimating multidimensional (MD) frequencies using prior knowledge of the signal spectral sparsity from partial time samples. In many application…
Spectral Method for Phase Retrieval: an Expectation Propagation Perspective
Junjie Ma, Rishabh Dudeja, Ji Xu +2
Phase retrieval refers to the problem of recovering a signal from its phaseless measurements …
Multi-target Position and Velocity Estimation Using OFDM Communication Signals
Yinchuan Li, Xiaodong Wang, Zegang Ding
In this paper, we consider a passive radar system that estimates the positions and velocities of multiple moving targets by using OFDM signals transmitted by a totally un-coordinat…
