Synchroabsorbing Transform

a time-frequency analysis post-processing method which can acquire highly concentrated TFR and relatively accurate amplitude of each mode.

These codes are related to the paper "Synchroabsorbing Transform with Application to Fault Diagnosis of Aerospace Engines", accepted by IEEE TIM but not published yet.

SAT.m is the main algorithm;

rSAT.m is the signal reconstruction of SAT;

example.m is the simulation example exhibited in the paper;

dataSim.mat is the data adopted in the paper;
