Applications of Engineering Technology and Science (AETS)
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.
