Abstract :
Compactly supported spline-wavelets are used to process simulated transient signals in a noisy environment. It is found that linear-phase spline-wavelets can be effectively used as near-optimal time-domain windows to localize the signal onsets. This technique does not require prior knowledge of the signal. Results are demonstrated numerically by the detection of signal arrivals in noise
