Title: Signal Processing in the Presence of Heavy-Tailed Extremes
Author(s): John P Nolan*
Companies: American University
Keywords: impulsive noise; stable distributions; signal processing
Abstract:

Algorithms are used to process voice communications, medical images, video, sonar, radar, and other types of signals. Standard algorithms can work poorly if the noise is non-Gaussian impulsive noise. We show that some real noise can be better modeled by a heavy-tailed stable distribution and that non-linear methods based on such models can improve results in such systems, reducing the risk of wrong decisions.
