Discrete Signal Processing on Graphs: Sampling Theory
Siheng Chen, Rohan Varma, Aliaksei Sandryhaila +1
We propose a sampling theory for signals that are supported on either directed or undirected graphs. The theory follows the same paradigm as classical sampling theory. We show that…

Algebraic Signal Processing Theory: Cooley-Tukey Type Algorithms for Polynomial Transforms Based on Induction
Aliaksei Sandryhaila, Jelena Kovacevic, Markus Pueschel
A polynomial transform is the multiplication of an input vector $x\in\C^n$ by a matrix $\PT_{b,α}\in\C^{n\times n},$ whose -th element is defined as for pol…
