Abstract：This paper proposes a method that can automatically obtain common lineshape in the spectrum data set based on Complex Principal Component Analysis(CPCA). which can correct frequency shifts and damping factor shifts effectively. This method aligns frequency at first, then extends CPCA to the correction of damping factor shifts in a single resonant peak across spectra. Through this method, frequency and damping factor alignment are successfully achieved. In terms of computation time and estimation precision this method is significantly better than that of PCA.
