A Topological Low-Pass Filter for Quasi-Periodic Signals

Year: 2016

Type: article

Abstract: This letter presents a two-stage topological algorithm for recovering an estimate of a quasi-periodic function from a set of noisy measurements. The first stage of the algorithm is a topological phase estimator, which detects the quasi-periodic structure of the function without placing additional restrictions on the function. By respecting this phase estimate, the algorithm avoids creating distortion even when it uses a large number of samples for the estimate of the function.
