iSMART: An Iterative Sampling-and-Regression Technique for Solving Martingale-Based PDEs
Tiejun Li, Xiaoguang Li, Fugui Ma
We propose the {\bf i}terative {\bf S}a{\bf M}pling-{\bf A}nd-{\bf R}egression {\bf T}echnique (iSMART) for high-dimensional martingale-based partial differential equations (PDEs)…
ST-DDA: Dynamic Channel Estimation in the Doppler-Delay-Angle Domain via Sparse Subspace Tracking for TDD Systems
Xu Zhu, Tiejun Li
Accurate full-band channel acquisition in frequency-hopping time-division duplex (TDD) systems is challenging because each sounding slot observes only a limited frequency subband,…
Covering-radius and Collinearity- Minimizing Pilots for Channel Estimation in TDD Systems
Xu Zhu, Yi Zeng, Tiejun Li
This letter studies pilot design for orthogonal frequency-division multiplexing-based time-division duplex (TDD) systems under a sliding-window latest-slot recovery framework that…
DDA-Net: Accurate TDD Channel Estimation via Deep Unfolding the Doppler-Delay-Angle Representation of Channel Signals
Yufei Ma, Xu Zhu, Tiejun Li
In TDD massive MIMO systems, channel estimation under sparse frequency-hopping pilots is challenging: each snapshot captures only one narrow pilot block that hops across frequency,…
Quasi-Newton OMP Approach for Super-Resolution Channel Estimation and Extrapolation
Yi Zeng, Mingguang Han, Xiaoguang Li +1
Channel estimation and extrapolation are fundamental issues in MIMO communication systems. In this paper, we proposed the quasi-Newton orthogonal matching pursuit (QNOMP) approach…
DMRA: An Adaptive Line Spectrum Estimation Method through Dynamical Multi-Resolution of Atoms
Mingguang Han, Yi Zeng, Xiaoguang Li +1
We proposed a novel dense line spectrum super-resolution algorithm, the DMRA, that leverages dynamical multi-resolution of atoms technique to address the limitation of traditional…
