Time-frequency Distribution and Spectrogram Rearrangement of Signal Analysis

摘要：

Time-frequency distribution of signal is researched and sevral rearrangements are compared. The TimeFrequency Toolbox (TFTB) in MATLAB is used. Simulation results show that rearrangement can restrain cross-terms and improve time-frequent aggregation.
