Fast Fourier Tansform (FFT) operation is required at the receiver side to perform signal transformation at higher rate when compared to that of DFT. The implementation of radix 4 FFT is performed in various methods namely butterfly method, Radix- r FFT and split radix FFT. In this paper, ...
Run the Radix-4 algorithm as a floating point implementation. The function radix4FFT1_Float.m accepts real or complex floating point inputs and calculates the FFT. S = radix4FFT1_Float(s); S = bitrevorder(S);% Calculate FFT using MATLAB functionY = fft(s);% Compare accuracy of Radix...

The decimation-in-time (DIT) radix-4 FFT recursively partitions a DFT into four quarter-length DFTs of groups of every fourth time sample. The outputs of these shorter FFTs are reused to compute many outputs, thus greatly reducing the total computational cost. The radix-4 decimation-in-freque...
