% The length of the input x must be an integer power of 2. % ex: in stage 1 loop is repeated 4 times , in stage 2 loop is repeated 2 times and so on while( n<=2 ...

A comprehensive implementation and performance analysis of six Fast Fourier Transform (FFT) algorithms applied to Orthogonal Frequency Division Multiplexing (OFDM) systems. This repository contains ...

Abstract: In this paper, an implementation of low-power, high-speed radix-2 DIT (decimation-in-time) FFT suitable for AAC/DRA audio decoding is presented. For low-power and high-speed considerations, ...
