Synchrosqueezing-based time-frequency analysis of multivariate data
Multivariate time-frequency algorithm using synchrosqueezing transform. By frequency partitioning, thus identifying multivariate monocomponent signals. In conjunction with the joint instantaneous frequency estimator. So as to represent multivariate data with a single time-frequency representation.
