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…
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…
Orbital Angular Momentum Waves: Generation, Detection and Emerging Applications
Rui Chen, Hong Zhou, Marco Moretti +2
Orbital angular momentum (OAM) has aroused a widespread interest in many fields, especially in telecommunications due to its potential for unleashing new capacity in the severely c…
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 …
Joint Timing Offset and Channel Estimation for Multi-user UFMC Uplink
Yicheng Xu, Hongyun Chu, Xiaodong Wang
Universal filtered multi-carrier (UFMC), which groups and filters subcarriers before transmission, is a potential multi-carrier modulation technique investigated for the emerging M…
