Discrete Sampling and Interpolation: Orthogonal Interpolation for Discrete Bandlimited Signals.
Year: 2014
Type: preprint
Abstract: Dedicated to the memory of Sivatheja Molakala Abstract—We study the problem of finding unitary submatrices of the discrete Fourier transform matrix. This problem is related to a diverse set of questions on idempotents on ZN, tiling ZN, difference graphs and maximal cliques. Each of these is related to the problem of interpolating a discrete bandlimited signal using an orthogonal basis.
