The Hilbert-Huang transform theory decomposes the signal adaptively into a finite number of intrinsic modes and residual signals that characterize the trend of the signal through empirical

Shaowei Zheng,Lijun Wang,Zuohua TangIFCB estimation is by averaging IFCB of all stations. However, this method doesn’t consider the variation of receiver IFCB, so the averaged receiver IFCB is lumped into satellite IFCB. If the receiver IFCB can’t eliminate by averaging when station number is limited, this method is not theoretical co
