Comments on 'Synchroextracting transform: The theory analysis and comparisons with the synchrosqueezing transform'

摘要

This is a comment on the paper titled "Synchroextracting transform: The theory analysis and comparisons with the synchrosqueezing transform". The theoretical analysis of reconstruction error of synchroextracting transform (SET) method is given whereas the comparison of reconstruction error between SET and synchrosqueezing transform (SST) is not listed in. Therefore, we re-give the derivation of the reconstruction errors of the two methods, and compare their approximate accuracy in this study.
