On the existence of optimizers for time-frequency concentration problems
Fabio Nicola, José Luis Romero, S. Ivan Trapasso
We consider the problem of the maximum concentration in a fixed measurable subset of the time-frequency space for functions . Th…
Spectral-norm risk rates for multi-taper estimation of Gaussian processes
José Luis Romero, Michael Speckbacher
We consider the estimation of the covariance of a stationary Gaussian process on a multi-dimensional grid from observations taken on a general acquisition domain. We derive spectra…
Efficient computation of the zeros of the Bargmann transform under additive white noise
Luis Alberto Escudero, Naomi Feldheim, Günther Koliander +1
We study the computation of the zero set of the Bargmann transform of a signal contaminated with complex white noise, or, equivalently, the computation of the zeros of its short-ti…
Spectral deviation of concentration operators for the short-time Fourier transform
Felipe Marceca, José Luis Romero
Time-frequency concentration operators restrict the integral analysis-synthesis formula for the short-time Fourier transform to a given compact domain. We estimate how much the cor…
