Support Recovery for Sparse Signals with Unknown Non-stationary Modulation
Youye Xie, Michael B. Wakin, Gongguo Tang
The problem of estimating a sparse signal from low dimensional noisy observations arises in many applications, including super resolution, signal deconvolution, and radar imaging.…
Atomic Norm Denoising for Complex Exponentials with Unknown Waveform Modulations
Shuang Li, Michael B. Wakin, Gongguo Tang
Non-stationary blind super-resolution is an extension of the traditional super-resolution problem, which deals with the problem of recovering fine details from coarse measurements.…
Simultaneous Sparse Recovery and Blind Demodulation
Youye Xie, Michael B. Wakin, Gongguo Tang
The task of finding a sparse signal decomposition in an overcomplete dictionary is made more complicated when the signal undergoes an unknown modulation (or convolution in the comp…
