Using a Fast Fourier Transform Algorithm
The symmetry and periodicity properties of the discrete Fourier transform (DFT) allow a variety of useful and interesting decompositions. In particular, by clever grouping and reordering of the complex exponential multiplications it is possible to achieve substantial computational savings while still obtaining the exact DFT solution (no approximation required). Many “fast” algorithms have been ...
متن کاملFractional-Fourier-transform calculation through the fast-Fourier-transform algorithm.
A method for the calculation of the fractional Fourier transform (FRT) by means of the fast Fourier transform (FFT) algorithm is presented. The process involves mainly two FFT's in cascade; thus the process has the same complexity as this algorithm. The method is valid for fractional orders varying from -1 to 1. Scaling factors for the FRT and Fresnel diffraction when calculated through the FFT...
متن کاملDesign of Biometric Fingerprint Image Enhancement Algorithm by using Iterative Fast Fourier Transform
Among all the minutia based fingerprint identification system, the performance depends on the quality of input fingerprint images. In this paper, we have designed and implemented an algorithm of fingerprint image enhancement by using Iterative Fast Fourier Transform (IFFT). We have designed an approach for removing the false minutia generated during the fingerprint processing and a method to re...
متن کاملPruning fast Fourier transform algorithm design using group-based method
In this paper, we propose the grouped scheme, which can be specially applied to compute the pruning fast Fourier transform (pruning FFT) with power-of-two partial transformation length. The group-based pruning FFT algorithm applies the scheme of the grouped frequency indices to accelerate computations of selected discrete Fourier transform (DFT) outputs. The proposed pruning FFT algorithm has f...
متن کاملThe Cooley - Tukey Fast Fourier Transform Algorithm ∗
The publication by Cooley and Tukey [5] in 1965 of an e cient algorithm for the calculation of the DFT was a major turning point in the development of digital signal processing. During the ve or so years that followed, various extensions and modi cations were made to the original algorithm [6]. By the early 1970's the practical programs were basically in the form used today. The standard develo...
