Abstract

in this paper, HILBERT HUANG TRANSFORM (HHT) for TIME SERIES analysis of the status of permanent GPS stations can be provided. HILBERT HUANG TRANSFORM and its, related spectrun is a new method for the analysis of nonlinear processes. This method represents not only a precision analysis in the time-frequency space, but also it declares the physics of the dynamic processes. This method has two speps. At the first step, the data is disintegrated into IMF elements by EMD method. At the second step Hilbert transform is applied for IMF elements and distribution of the time-frequency-Hilbert energy SPECTRUM is then determined. In this SPECTRUM, Location, frequency and energy defined by time events for the Hillbert transform will be reserved. So instantaneous frequency will have a major role in this method.
