摘要：Recently digital signal processing has received high attention due to the advancement in multimedia and
wireless communication, The FFT processor is the most speed critical part in the multi-carrier orthogonal frequency
division multiplexing (OFDM) communication system. The FFT (fast Fourier transform) processor is the most speed
and power consumption critical part in the orthogonal frequency division multiplexing (OFDM) communication
system , In these systems, low power is usually one of the major concerns. Accordingly Orthogonal Frequency Division
Multiple Access (OFDM) technique based on Time Division Duplex (TDD) is an attractive technology for high data
rate wireless access in multi channel communication, The modulation and demodulation of OFDM are done by Fast
Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT) respectively. The FFT (fast Fourier transform)
processor is the most speed and power consumption critical part in the orthogonal frequency division multiplexing
(OFDM) communication system we also propose a design new FFT algorithm for the implementation of multiplier that
is to be used in radix 25
512-point.
