摘要
En 中文
Discrete Fourier transform (DFT) is widespread used in many fields of science and engineering. DFT is implemented with efficient algorithms categorized as fast Fourier transform. A fast algorithm is proposed for computing a length-N = 6(m) DFT. The proposed algorithm is a blend of radix-3 and radix-6 FFT. It is a variant of split radix and can be flexibly implemented a length 2(r) x 3(m) DFT. Novel order permutation of sub-DFTs and reduction of the number of arithmetic operations enhance the practicability of the proposed algorithm. It inherently provides a wider choice of accessible FFT's lengths.
