Transient detection, higher-order time-frequency distributions and the entropy
Pierre‐Olivier Amblard, Jean‐Louis Lacoume, Jean-Marc Brossier · 2002
The authors deal with the use of higher-order time-frequency distributions for the detection of transient signals. They show that a recent method is linked to those objects and also related to information measures. They then propose an heuristic method to detect transients. This method uses a new adaptive estimator of the fourth-order cumulant that they study in details, before presenting simulations that validate the detection method.>
