基于同步压缩的多变量数据时频分析 matlab

Files: Filename: multi_sst_TF_main.m The main implementation of the multivariate time-frequency representation based on the synchrosqueezing transform. The complementary files used for this matlab file are: multi_bandwidth.m and multi_bandwidth_check.m Filename: sst_wavelet_linear.m Linear implementation of the wavelet based synchrosqueezing transform. Filename: cwavelet_transform.m Continuous wavelet transform implementing both the morlet and bump wavelets. Filename: example_code.m This file provides 4 multivariate time-frequency representations, illustrating the performance of the algorithm. -The first simulation consists of bivariate noisy sinusoidal oscillation with a small frequency deviation between each channel. - The second simulation consists of bivariate frequency modulated oscillation with a small frequency deviation between each channel. -The third simulation consists of float drift data. -The fourth simulation consits of bivariate doppler radar data pertaining to the motion of a robotic device.
