The Fast Fourier Transform (FFT) is a widely used algorithm that computes the Discrete Fourier Transform (DFT) using much fewer operations than a direct implementation of the DFT. FFTs are of great ...

Abstract: A mixed radix algorithm for the in-place fast Fourier transform (FFT), which is broadly used in most embedded signal processing fields, can be explicitly expressed by an iterative equation ...

Abstract: In this paper, we propose an efficient variable-length FFT processor architecture suitable for multi-mode and multi-standard OFDM communication systems. The FFT processor is based on radix-2 ...

This is a preview. Log in through your library . Abstract Apart from the fact that they are both ingenious and remarkably efficient, there would appear to be little kinship between fast Fourier ...
