Time-FrequencY by Convex OptimisatioN

Contents

This repository contains all the MATLAB files necessary to perform the algorithm TYCOON (Time-frequencY by Convex OptimizatioN). The theoretical background relative to the algorithm can be found in the following paper:
[1] M. Kowalski, A. Meynard and H-T. Wu, "Convex Optimization approach to signals with fast varying instantaneous frequency", Applied and Computational Harmonic Analysis, vol. 44, pp. 89-122, Jan. 2018, available online.

Descriptions of the different folders:

• AlgorithmTYCOON: TYCOON functions.
• OtherMethods: Other time-frequency analysis algorithms like Empirical Mode Decomposition and Synchrosquuezing.
• PerfEvaluation: functions to evaluate the quality of the time-frequency representation.
• scriptsTYCOON: scripts implmenting TYCOON on example signals.
• SynthSig: functions to synthesize the signal used in the paper to perform TYCOON.
