Choice of sampling interval and extent for finite-energy fields

Gulcu, T. C.; Özaktaş, Haldun M. (Institute of Electrical and Electronics Engineers Inc., 2017)

We focus on the problem of representing a nonstationary finite-energy random field, with finitely many samples. We do not require the field to be of finite extent or to be bandlimited. We propose an optimizable procedure ...
Optimal representation of non-stationary random fields with finite numbers of samples: A linear MMSE framework

Özçelikkale, A.; Özaktaş, Haldun M. (Elsevier, 2013)

In this article we consider the representation of a finite-energy non-stationary random field with a finite number of samples. We pose the problem as an optimal sampling problem where we seek the optimal sampling interval ...
