Abstract: A new lower bound on the average reconstruction error variance of multidimensional sampling and reconstruction is presented. It applies to sampling on arbitrary lattices in arbitrary dimensions, assuming a stochastic process with constant, isotropically bandlimited… read more here.

DOI: 10.1109/lsp.2022.3142677
Abstract: We propose a scheme for analog-to-digital (A/D) conversion of a signal that is bandlimited most of the time but contains harmonics of a high frequency occasionally. To enable the capture of the high frequency components,… read more here.

DOI: 10.1109/tit.2021.3057672
Abstract: The bandwidth of a bandlimited signal is an important number that is relevant in many applications and concepts. For example, according to the Shannon sampling theorem, the bandwidth determines the minimum sampling rate that is… read more here.
