Recovery of periodicities hidden in heavy-tailed noise

Illya M. Karabash, Jürgen Prestin

We address a parametric joint detection-estimation problem for discrete signals of the form $x (t) = \sum_{n = 1}^{N} α_{n} e^{- i λ_{n} t} + ε_{t}$ , $t \in N$ , with an additive no…

Sharp estimates of approximation of periodic functions in Hölder spaces

Yurii Kolomoitsev, Jürgen Prestin

The main purpose of the paper is to study sharp estimates of approximation of periodic functions in the Hölder spaces $H_{p}^{r, α}$ for all $0 < p \leq \infty$ and $0 < α \leq r$ . By using mo…
