Fast Algorithm for Adaptive Chirplet Decomposition
A rapid algorithm for adaptive chirplet decomposition, addressing the challenges of numerous unknown parameters and implementation difficulties. This algorithm computes the quadratic phase function of signals to determine energy concentration along chirp rate curves, enabling simultaneous estimation of chirplet parameters (chirp rate, time center, and amplitude) via spectral peak detection. Initial frequency and bandwidth estimates are obtained through de-chirping techniques. The effectiveness of this method is validated through simulation results.

Fundamental Concept of the Fast Median Filtering Algorithm Proposed in This Paper
The core principle of the fast median filtering algorithm introduced in this paper is that during the sliding window movement process on the original data sequence, the current window only needs to remove its earliest element and incorporate the new element following the window to form the content of the next window. This implementation corresponds to pre-packaged algorithm code in MATLAB, designed for optimized computational efficiency.
