Detection of Transients in Noise with the Undecimated Discrete Wavelet Transform
Thomas T. Liu, Antony C. Fraser‐Smith · 2000
A method based on pattern matching in the undecimated dis- crete wavelet transform domain is introduced for the detection of a known transient with unknown parameters in the presence of noise. Maxima tracking techniques are used to reduce the computational complexity of the matching procedure by an order of magnitude, with minimal performance impact.
