A minimum squared-error framework for generalized sampling
TLDR
We treat the problem of reconstructing a signal from its nonideal samples where the sampling and reconstruction spaces as well as the class of input signals can be arbitrary subspaces of a Hilbert space. Expand

Nonlinear and Non-Ideal Sampling : Theory and Methods
We study a sampling setup where a continuous-time signal is mapped by a memoryless, invertible and nonlinear transformation, and then sampled in a non-ideal manner. Such scenarios appear, forExpand

Minimax Approximation of Representation Coefficients From Generalized Samples
TLDR
We consider the problem of approximating L2 inner products, i.e., representation coefficients of a continuous-time signal, from its generalized samples, by proper processing of the given sample sequence. Expand
