Determination of compactly supported functions in shift-invariant space by single-angle Radon samples

Youfa Li, Shengli Fan, Deguang Han

While traditionally the computerized tomography of a function $f \in L^{2} (R^{2})$ depends on the samples of its Radon transform at multiple angles, the real-time imaging s…

Phase retrieval of analytic signals from short-time Fourier transform measurements

Youfa Li, Hongfei Wang, Deguang Han

Analytic signals constitute a class of signals that are widely applied in time-frequency analysis such as extracting instantaneous frequency (IF) or phase derivative in the charact…
