Implementation of Radix 4 DIF-FFT algorithm based on DSP
首先介绍了频率抽取基4FFT算法的快速有效的原理及实现方法，提出了一种在DSP上实现此算法的方法并且在TMS320C6713B浮点型DSP上实现了频率抽取基4FFT算法，最后对语音信号进行了基4FFT变换和反变换的实验，实验结果表明本程序能正确、高效地实现基4FFT变换与逆变换的算法。
he design principle and realization of a Radix-4 Decimation-In-Frequency fast Fourier transform (R4-DIF-FFT) algorithm is introduced. A method that uses DSP to realize the algorithm and the implementation in floating-point DSP TMS320C6713B is put forward. At last an experiment of FFT and IFFT on speech signal is make. The result validates the correctness and high-efficiency of the implementation of R4-DIF- FFT algorithms.
