New Spectrum Correction Method Based on Chirp Z Transform

A new spectrum correctionmethod based on Chirp Z Transform is presented, by which the frequency resolution can beincreased according to users' requirements and thus a richer spectrum can be obtained andmore accurate spectrum peaks can be found. This method limits the errors when the discretefrequency lines can't catch the real spectrum peaks. The basic principle of Chirp ZTransform and its application in spectrum correction are introduced in the paper andsimulations are also carried out in order to verify its validity. Simulation results showthat the new spectrum correction method owns the advantages of high accuracy, high speedand high flexibility.
