Abstract :
Wireless 4G and 5G technology is required more spectrums and advanced antennas to achieve high speed in mobile and other application. Multiple Input Multiple Output (MIMO) OFDM technique is used to improve the Spectrum efficiency with least effort. The main component of MIMO OFDM transceiver is Fast Fourier Transform (FFT). FFT is used to transfer time domain information into frequency domain. In this paper, the analysis of Radix2, Radix4, Mixed Radix4-2 and Mixed Radix8-2 FFT is presented to find area, delay and frequency. Radix4 and Radix2 are combined in Mixed Radix 4-2 to provide less area and high speed than all other FFT structure. Simulation is carried out by ModelSim6.3c and synthesis is processed by Xilinx10.1.
