A discretization-free sparse and parametric approach for linear array signal processing
Zai Yang, Lihua Xie, Cishen Zhang
Direction of arrival (DOA) estimation in array processing using uniform/sparse linear arrays is concerned in this paper. While sparse methods via approximate parameter discretizati…

Robust Compressive Phase Retrieval via L1 Minimization With Application to Image Reconstruction
Zai Yang, Cishen Zhang, Lihua Xie
Phase retrieval refers to a classical nonconvex problem of recovering a signal from its Fourier magnitude measurements. Inspired by the compressed sensing technique, signal sparsit…

Sparse MRI for motion correction
Zai Yang, Cishen Zhang, Lihua Xie
MR image sparsity/compressibility has been widely exploited for imaging acceleration with the development of compressed sensing. A sparsity-based approach to rigid-body motion corr…
