Mobile WiMAX (IEEE 802.16e standard) is widely used for configuring wireless Metropolitan Area Network (MAN) which uses Orthogonal Frequency Division Multiple Access (OFDMA). Orthogonal frequency division multiple access is a multiuser version of the popular Orthogonal Frequency Division Multiplexing (OFDM) digital modulation scheme. FFT is one of the important blocks used in OFDMA systems. This paper presents implementation of a 1024-point Fast Fourier Transform (FFT) processor for Mobile WiMAX. Radix 22algorithm is proposed and used for the OFDM communication system.
