How to get high resolution results from sparse and coarsely sampled data
Annie Cuyt, Wen-shin Lee
Sampling a signal below the Shannon-Nyquist rate causes aliasing, meaning different frequencies to become indistinguishable. It is also well-known that recovering spectral informat…

VEXPA: Validated EXPonential Analysis through regular sub-sampling
Matteo Briani, Annie Cuyt, Ferre Knaepkens +1
We present a procedure that adds a number of desirable features to standard exponential analysis algorithms, among which output reliability, a divide-and-conquer approach, the auto…

A hybrid Fourier-Prony method
Matteo Briani, Annie Cuyt, Wen-shin Lee
The FFT algorithm that implements the discrete Fourier transform is considered one of the top ten algorithms of the th century. Its main strengths are the low computational cos…
