Efficient 16-points FFT/IFFT Architecture for OFDM Based Wireless Broadband Communication

M. Arioua, S. Belkouch and M.M. Hassani

The Fast Fourier Transform (FFT) and its inverse transform IFFT processors are a key component in OFDM based wireless broadband communication systems. Hence, it is important to develop a low-power and high-performance FFT/IFFT processor to meet the requirement of low cost and real time in such communication systems. In this study, an efficient 16-points FFT/IFFT module is developed to build a large FFT/IFFT processor for OFDM based communication system (IEEE 802.16). The 16-point FFT architecture consists of an optimized pipeline implementation based on Radix-2 butterfly Processor Element. This proposed architecture reduces the multiplicative complexity and power consumption compared to other efficient architectures. The FFT processor has been implemented in VHDL code. The simulation results show that this processor significantly achieves a better performance with less complex multiplications and lower resource usage.
