| Abstract: | The correction of phase error is an important step in the calculation of Fourier transform spectrum. The problem of computation efficiency of the commonly used phase correction method, Mertz method, is studied in detail. By applying the quality of real serial Fast Fourier Transform (FFT) and combining it with the computing process, an improved algorithm is obtained, which demonstrates greater computation efficiency and is easier to use. |
