The Real-time Fast Algorithm of the Zero Interpolation in the Arithmetic Fourier Transform
Arithmetic Fourier transform, for its little multiplication calculation and no restriction of the sample points, has a better application prospect in the harmonic analysis. And the main factor influencing the AFT operation speed is the zero interpolation points’ calculation, this paper mainly studies the off-line calculation problem of zero interpolation location, it can reduce the online calculation of AFT, and improve the real-time calculation speed of the zero interpolation algorithm in the harmonic analysis.
