Paper Abstract

We demonstrate the use of a wavelet-based system for detection and characterization of transients. Traditional matched filtering is implemented in the wavelet transform domain, providing us with efficient algorithms with potential for reduced noise and improved signal separation. These O(N) algorithms have been applied to experimental data from a sea trial, demonstrating their potential for online analysis of sensor data in health monitoring systems.
