A self-adaptive HHT decomposition method and a dynamic adjustment stop condition are proposed.
A novel framework is presented for the purpose of filtering out useful components of a signal within frequency domain contrasting with certain sample data.
For the first time, the characteristic scale of HHT decomposition is proposed, which can be used to recongize and segment different porcesses from the sophiscated and mixed sample data in a large area in which multi geophysical models work together.
