Purification of Axis Trace by Harmonic Window Decomposition

摘要：

Aiming at the purification of axis trace, a novel method free from decomposition was proposed by using the harmonic window decomposition. Firstly, the sampled data was transformed by FFT in frequency domain. Secondly, the interested frequency band had been selected, which was the edge of harmonic window decomposition Thirdly, the needed frequency components could be abstracted by harmonic window decomposition and reconstructed in time domain, so the purification of axis trace in one or more interested frequency bands could be realized. Simulation and practical results show the advantage of harmonic window decomposition. This method also has simple algorithm and high calculating speed; it provides a new method for purification of axis trace.
