Design of 64Point Fast Fourier Transform by Using Radix-4 Implementation
The Fast Fourier Transform (FFT) is very significant algorithm in signal processing, to obtain environmental status and wireless communication. This paper explains the high performance 64 point FFT by using Radix-4 algorithm. Radix-4 has the advantage of parallel computations. This is simulated using VHDL, using Xilinx ISE 10.1 and simulated using ModelSIM6.5e. Here, the authors shown the architectures of 32 point FFT withradix-2 and 64-point FFT with radix-4. Finally, the high performance 64-point FFT processor their architecture and simulation graphs are shown.
